FWIW, I had a Lee 4 hole turret auto indexing for a few years. I had no problems with it. It loaded good pistol ammo at a rate of about 200/hr, which was more than fast enough at the time. I never needed to tweak or adjust, it just worked for about 3000 rounds. It wasn't what I'd call "sturdy," so I got a Redding turret for rifle ammo but now that I'm getting into "massive quantity" pistol shooting, I think a progressive is in order.
I really want to try the Lee Pro 1000. You can get a factory refurb with dies for $80. If it doesn't work it can be sold on e-bay for more than retail like the 4 hole turret I had. Since that's probably where it will end up, I will most likely save myself the trouble and get a Dillon of some kind.
