I helped a friend set up his Lee Classic Cast Turret this fall, his first foray into reloading. 308 Win.
For rifle it is the best thing going for a beginner. We did not do pistol, but I can only assume that with carbide dies it would be even quicker.
The cost of the press will be made back in his first 500 reloads easily, with pistol it would take a bit more (depending on caliber).
I do not recommend a progressive for a new reloader, and anyone who wants to load for volume doesn't want a single stage. So the Lee turret makes a lot of sense as a first press.
Machine guns are awesome until you have to carry one.
