You asked the question and now you are going to get a bunch of replies Doc! My experience I thought single stage but just seemed to be time consuming, and (you gotta make time for your studying!) I thought to even start loading on a 1050, spend 3K for the press and all the equipment I would need to get started and that's just one caliber(guessing)!.. I started looking at the 650 and the # of rounds I can crank out in an hour but the conversions boosted the price up just to upgrade! And I looked at the 550 I know I wanted to load for more then 5 handgun calibers (so the SD was out the question+ I planned on loading rifle) I also go to school and work a full time job and have kids(5-1/2) so the 550 is the direction I went!what does family & school have to do with it? I don't know but I got a pile of ammo I shoot every week or two I shoot out a few hundred, that my progressive press kicks out with no problem! I have been reloading for about 6 month so I am still a newbie. The 550 is easy to set up and use!what ever you decide to load on its going to spend money, the initial setup is what you got to get past, once you do everything should be a breez! You mentioned shooting at matches, most people reload that shoot in matches. Maybe hookup with a few guys who reload and also buy some components(powder,primers bullets and brass) ask if they can show you thE ropes I'm sure they would not mind! Especially if you buy em a beer or two!good luck! I don't wonna tell you what to get but, Get a Dillon RL550B! Lol...
