I also like the Lee turret press and believe this is the only Lee press worth looking at.
The 4 hole is a waste since you'll end up with either an empty station or be horribly frustrated trying to use that disgusting excuse for a primer feed. Better to get a 3 hole unit and resize in batches with the auto-index feature removed (takes about 10 seconds), then prime using a hand priming tool. After that, stick the auto-index rod back in and load semi-progressively.
You can handle at least 500 round a week with this press(I can do about 350/hour with primed cases) and I'd be shocked if you could ever manage to break anything. I've loaded at least 40,000 rounds on mine and prefer to use it over my Dillon 650 unless the quantities involved are over 1000. I've still got some plastic spare part that I've yet to use. The Dillon is a fine tool, but I prefer to reload, not be a machine operator.
The auto-disk powder measure that would come with the $100 or less turret kit will do an excellent job, mainly because the turret rotation will cause the powder to settle really consistently.
I've got presses from every manufacturer out there I think, and am of the opinion that no press OR brand is made for everyone. The number of reloaded ammo failures I've been seeing lately tell me that not everyone should run out and buy a Dillon(certainly not as a first press) as not everyone is disciplined enough to use one.
Back to the Lee press. The 4 hole feature is supposed to be for the sizer, expander, bullet seater, and factory crimp die. While this is possible, the priming "mechanism" is simply a "T" shaped piece of metal that requires you to place a primer on it by hand each time. I can't see that this is a practical way to do things. Resize in batches, tumble the cases, hand prime them, then load using the expander/powder die, the seating die, then the factory crimp die.
