I have a Rockchucker, Lee Classic cast, RCBS turret and a Hornady LnL AP set up in my reloading room.
I bought the Lee Classic to reload 50 BMG- it resizes those big cases easily. I also use it for sizing/depriming other rifle brass and low volume pistol brass because of the spent primer system. Higher volume pistol brass is deprimed on the LnL because it is faster with the case feeder.
Before I bought the Lee Classic, I used the Rockchucker for depriming. It is a great press and has served me well for many years. I still use it for load development for some rifle rounds and sizing cast bullets.
I use the RCBS turret for load development when I need to use more than on die (i.e. a flaring die followed by a seater). I prefer to load one round at a time (flare, charge, seat, repeat) to avoid double charges or no charges. I set all the dies once and load as many rounds as I need without changing dies. The turret has a primer seater, but I prefer to prime off the press, so I don't use it often.
I am not a marksman- all of the rounds I load are much more accurate than the shooter, so any advantages offer by the more expensive presses are lost on me. FROGO207 is absolutely correct, and you can't go wrong with either press. If money is an issue, the Lee Classic Cast is a great value and I'm sure you will be happy with it.
