I can give some advice, I got started with the RCBS kit. It doesn't have all you'll need by any stretch, so it may behoove you to put together a list (get help on here, Padom is a mod on here and has tons of good advice even for experienced loaders) and then buy some of it used. A better press can be bought alone, and used for a good price. People upgrade and sell stuff all the time. I'd look at the kits and then get the better parts you'll use for a long time vs. stuff that gets upgraded and sits. When I got my RCBS kit, it got me started cheaply but was far from complete. If on a budget, and planning to upgrade later, a kit can be worth it but for the love of fuck, PM me before you buy a new one, I can save you a lot of money on one of these basic kits and/or parts to get started.
Press. I'd get a Forster Co-Ax. That's a damn nice press. Or maybe an RCBS Ammomaster --it's single stage made for .50 so that means it'll be more than powerful enough and easier to work smaller cases. You'll use the single stage even if you upgrade to a Dillon. I still use my little Rock Chucker all the time for pulling, depriming odd cases, swaging .50, etc. A single stage is good to learn on so you can focus on each step and it usually yields more accurate ammo in general, especially for beginners, though a 650 can roll amazing ammo.
Scale. I'd get the dispenser and scale combo and be done with it. I have a beam scale and trickler and measure that just sits, though that setup will work fine if used right. I used it to check the digital one but the weights and calibration always is dead on so it's not needed. The auto dispenser and scale is indispensable, I still use it with the 650 for working up loads all the time. With the single stage, it helps reduce or eliminate under or over charges since you work one at a time. Under charges can mean stuck bullets, happened to me early on, doesn't anymore.
Priming. I use press primers, but hand primers I hear have a better "feel" and you can use watching TV if you like. This is up to you. You'll want a primer tray, I'd get the metal Dillon one (it won't spark).
Case holder. IF you use one of these and it's not a bad idea, I'd just take a 2x4 and drill the appropriate size holes and use that, or drill a 1x4 all the way through and glue it to another one and do it that way. Cheap, custom and works better.
Funnel. Plastic ones are okay and it's what I use, but I'd rather have the one Satern Custom Machining sells. It's non-sparking metal and just a better funnel.
Calipers. I'd get good ones here, I have a set of probably 60yo. Mitutoyo's, came in case with thin copper adj. tool (so dial will always line up TDC, AMAZING this wasn't lost and means it was taken care of) and they are dead on accurate. I have a set of cheap Frankford Arsenal calipers and they work fine too, I dedicate them to Hornady headspace and COAL gauges. Digital or dial, digital is certainly easier but get a good brand, get what machinists use, not what reloading suppliers sell. Good ones can be had at pawn shops, but they like to charge new prices for old junk. I happened to get a good deal 25 years ago, but I consider that lucky. This is probably the most important tool IMO. It's used for everything.
Gauges. I'd get Wilson headspace gauges to start with. They are easy to use and measure case length and trim length at a glance and can be measured with calipers to get dead-on measurements. Most people misuse these and don't understand the value. I can't impress on you how important these are. They are used to setup your sizing dies if those are to be setup accurate, otherwise you don't know what it's doing. Same with trimming. Hornady gauges are preferred by some, they don't measure trim length but can do other things Wilson gauges can't. They're not too expensive, worth getting later on. I'd get the Wilson gauges for any round you plan on loading for right now. Again, you can't setup the dies without these.
Dies. I like the Forster micrometer dies. You want to get good ones and be done with it. Note different calibers can come in different sizes. NM, FL and SB. You want to start with FL (NM doesn't mean "better" here). If an SB seater is needed, just get one but only if needed. Bushing and neck dies can be added later if you go that route, or you can use them right away if you have some help and know what to get and how to use 'em. In general, a FL sizer and a good seater are what's needed, it doesn't need to be a micrometer seater but they are accurate and easy to setup. For crimping, get the Lee "Factory Crimp" dies. Cheap and they work really well, better than using the seater IMO/E.
Brass prep. RCBS case prep is something handy if using a single stage and doing it all by hand. You can do all the operations at once. Hornady makes a nice one but it costs more. Or you can get the stuff to do it by hand. You'll need a trimmer, again if doing this by hand and not planning on a Dillon anytime soon, get a good one. A good trimmer like a Giraud or something is the way to go here. You want it to have a motor, you want an accurate one. Some can be used to turn the necks if you get into that later.
Brass cleaning. A vibratory tumbler and corn cob and walnut media work great to start with or for smaller amounts. Still, I'd get a bigger one, perhaps the Dillon. Dillon also has a media separator which is handy to have but not exactly necessary. Ultrasonic also works well, Hornady makes one I have and it'll clean parts too. With the solution they sell and the machine on hot water, it really cleans the brass and fast. If cleaning a lot (like a drum of .50 and tens of thousands of other cases) a cement mixer and steel pins is nice. I'd start with the vibratory tumbler because it can be used for smaller or larger amounts of brass and you can use it to safely clean loaded ammo (though they recommend not to) or bullets.
I know I'm leaving something out, but for a beginner that wants to get the right stuff the first time and stuff they'll be able to use if/when they upgrade, this is the way to go IMO and wish I'd known this but even 15 years ago there wasn't as many options as there are today. It'd be best to go straight to a 650 but you'd miss so much that you learn on the single stage; it sucks but it's how it is. Unless you know someone that has one and can spend one on one time with you.
PM me if I have any gear you can use: I have a lot of stuff laying around I'd be willing to sell to get you started if you PM me. I have a sale going right now but don't have that listed. I can sell you an RCBS powder dispenser, 5-0-5 scale and trickler, a loading block, funnel and a primer tray, all RCBS. I have a set of RCBS standard FL .308 dies and a set of RCBS SB 5.56/.223 dies (for AR's) and an older set of .45ACP dies. I have a used but fine Lyman tumbler and a slightly used RCBS case prep station with tools. I'd even be willing to sell my RCBS press and priming kit. Basically, I can sell you the RCBS kit for less than you can buy it for and you won't be out near as much when you go to upgrade and can spend your money now on the other important items, like gauges and calipers and such. I wish I had this option when I got started.
