I have been running a Lee classic turret for a couple years. I have no issues with the auto indexing. It was spot on out of the box, and I haven't had to touch the adjustment of it since. Get a couple of the plastic bushings, they are very inexpensive (less than a buck each), and act like a fuse to keep you from over stressing other components when indexing. When they wear out, the indexing will get hinky. I have worn one out trying to back up the turret the wrong way. Once I figured out the right way to do it, the current bushing has been in there quite a while.
The only issue I have had with mine was the primer arm was titchy about adjustment and the top of the primer would occasionally hang up when the arm entered the ram. I made a very small spacer out of wood and put it where the arm pivots. No problems since I did that over a year ago.
Having a 5th hole in the turret would be nice for one of the calibers I use. I like to have a powder check die in the mix, and I use a factory crimp die on one of my handgun calibers. That doesn't leave room for both. Of course, with a 5th or 6th hole, that means one, or two more pulls of the handle when loading in continuous mode. I don't use an FCD for my revolver rounds, so I have enough space to accommodate all needed dies.
If I were to go back to batch mode for all my reloading, I would still load on my turret. The hassle of changing out each die with each operation change, would be a royal pain for me now.
For right at $100, it is an awesome machine. It is not perfect, but then even the big buck machines aren't. If you must have the be all, end all press, then probably best to look elsewhere. If you want a sturdy machine that works well, I highly recommend it.
