I started with a 550B, then bought a couple Rock Chuckers. I use them as much as the Dillon. Sizing/decapping is far handier on a single stage. I trim on one too. I found the trimmed length varied much more using the Dillon, so I bought a used RC and use it dedicated to the Dillon RT1200. It is very handy to just start trimming .223 w/o having to adjust anything--just hook up the vacuum and fly. If you aren't in a hurry, used presses crop up. I have bought them at gun shows, of course, but also on ebay, and occasionally just through conversations with others. My best one yet is a second 550B that I bought for $50.00. The guy's wife was going to throw it out (moving), so a buddy and I gave him $100 for the press and a ton of Dillon dies, scale, etc. I got the press, my buddy got the other stuff, as he wanted a 650. Now I have one for small primers and one for large. Hehe
