I am super new to reloading, so take what I say with a block of salt. I went with a single stage, for no other reason than cost. I was not sure if I would like it, although I had a feeling I would because I tend to like things that involve gear, process and ritual. So I went with a Lee Challenger Breech Lock kit. After I purchased brass, lead, powder, primers, dies, a manual etc I was at $375. I load .45, .357 and .38 (right now, I plan on adding 9mm soon). After loading a few weeks, I am sure at some point I will buy a progressive, but I am sure I will keep the single. I can see this turning into as much of hobby as the act of shooting itself. If you have the cash and think you will really like, a progressive would be nice but as a newb there looks like there is more that could go wrong.
