I had a Lee LoadMaster for years, reloaded all sorts of handgun rounds on it. The two greatest things on it are the automatic case feeder and the auto-indexing feature. The two worst things on it are the primer feeder and the primer feeder (ha!). It tended to be a little "fiddly", but I sure loaded a LOT of ammo on it.
I finally sold the LoadMaster and bought a Dillon 550. No auto casefeeder (unless you want to spend big extra bucks) and is not auto-indexing. The Square Deal IS auto-indexing, if I understand correctly.
Anyway, I don't miss the auto indexing, and I don't miss the auto casefeeder very much. I don't time myself, but loading 100 rounds doesn't take long. 15 minutes tops, I'd say. For me, the priming system is a better system with the primer being contained in a cup which is, in turn, aligned by the shell plate. It doesn't prime with the same motion that sizes, feeds powder, seats, and crimps, but requires a separate action after the handle is returned to the "up" position. I like it because I can feel the primer seating.
I've never used a Lee Turret press, so I can't comment.
Single stage is great and I have a Lee Classic Cast press for that, but if you want to load any kind of volume at all, a progressive is the way to go.
