Re: Square Deal B?
I use a SDB for all my handgun reloading needs and it suits me quite well. If and/or when I choose to upgrade, it'll be to either a Dillon 650 or a Hornady LnL AP (probably the LnL...with a case feeder). It'll definitely NOT be the non auto-indexing 550 due to it's lack of an auto-indexing feature. Although I certainly can't argue with Grumpy61 about having one each for large primers and small, it really isn't that hard to change. Probably a 15-30 minute procedure (depending on how often you've done it) to completely change from a small primer'd cartridge to a large one, to include changing the priming system, shell plate, and toolhead. I'd rather have two powder measures to eliminate the need to recalibrate it when changing cal's, but get by with only one just fine.
One thing to factor into your decision is the point made by lumpy grits, the SDB uses dies proprietary to Dillon. Dillon will be your ONLY source of dies for a SDB. A separate toolhead for each caliber is STRONGLY recommended so that you only have to set up the dies one time.
If the 550 is within your budget, I'd strongly consider the LnL AP from Hornady if you can swing it. I haven't used one, but am strongly leaning towards getting it to upgrade from the SDB simply for the ability to load rifle cartridges and for the ability to add a case feeder. It gets reviews comparable to those of the Dillon 650.
Good luck with your decision.
