Re: buying my first AK
Some good information and a little bit of not so good information has been posted. I'm new on this site, but know a bit about AKs, so I'll throw my recipe into the mix.
I shoot 5.45 almost exclusively. Why? It's cheap and easier to shoot and share. My little girlfriend can shoot the AK74 (5.45) more easily than the AK47 (7.62), so I bring what we both can use. Bulgarian AK74s are the best, and availably inexpensively. AIM Surplus, Tennessee Guns International, and others have them for a good price nowadays. Attempt to find one with the original barrel adn not a US replacement. Tantals are good but be wary...Century Arms International (CAI) uses screwy barrels (some say .223) that will keyhole. Avoid them at all costs. My Tantal was a home build on a Nodak Spud receiver and is fantastic. My two Bulgarian sidefolders use Nodak receivers, one is a home build and one is from Ohio Rapid Fire, and both shoot great. VERY compact, but not as comfortable as a fixed stock. My '74 fixed stock is an ORF build as well, and it has the rail on the left side to mount an optic, which is a bonus.
With that said, the 7.62x39 AK47 is not a hard gun to shoot. Ammo is down to .20 a round, and is plentiful. The WASR-10 should be AVOIDED. It's reliable only based on the AK itself being reliable, but it's poorly made in Romania and modified here in the states. Romanian AKs are the cheapest, and DO NOT HAVE CANTED SIGHTS just based on being Romanian! Poorly made AKs have canted sights (usually WASRs, SAR-1s, and other Century builds). Chinese AKs are arguably the highest quality, and as already stated, the MAK-90 is an excellent choice. They do not have the flash hider, bayonet lug, or pistol grip, but if you don't need these evil features it's an excellent choice. Of all my 7.62x39s, including a Russian PLO build and a Polytech Legend, my Mak is my favorite shooter. Do not stress over milled vs. stamped receiver...both are just fine, though the milled is generally smoother cycling. Understand that if you get a Mak90 and put a pistol grip stock on it, you must swap out some of the Chinese parts with US parts for compliance with Federal law 922r, and putting a US fire control group in the Mak detracts from the quality.
If you plan on using optics with your AK, decide now. If you want a scope on it, you're limited in options for mounting. Top covers with rails are generally low quality and not very stable. Gas tube/foreend rails are pretty far forward. The best in my opinion are the previously mentioned scope rail mounted on the left side of the receiver. If you're just gonna run irons or a red dot for closer quarters, you'd be fine with these mounting options.
If you get a home build, make sure it's made by someone that knows what they are doing, make sure it's 922(r) compliant, and checked for headspaced. Just because it's matching does not necessarily mean it's headspaced properly. Go/No go gauges are convenient to have when getting a built AK.
If you want an AK47, and can afford it, a nice Norinco preban rifle or Mak90 is probably your best choice for collectability and function. Arsenals and others are fine, but usually more expensive than they need to be. If you want an AK74, I'd stick with a Bulgarian build or Saiga (original Russian sporter rifle reconfigured back to AK47 style). Take some time to paruse

Sorry so long winded.
