I've got the Lee Classic Turret (the iron and steel one) and feel it's a great press for the money, too. $85 at Midway right now, as a matter of fact (though currently "out of stock, backorder OK").
I like to use the Auto Disk powder measure with it. You can get an adjustable drop meter that will allow you to drop any specific charge you want. And it's a very accurate measure, due to the way it works. However, it doesn't work real well with stick (usually rifle) powders, and Trail Boss seems to cause trouble due to the large grain size. This measure mounts directly to the top of the Lee "Powder-Through" expander die and is actuated when you run the case into the die. Nice, simple system.
The one weak link in this press, imo, is the "Indexing Ratchet", the fru-fru name they've given the little square of plastic that sits inside the turret and acts as a bushing to the auto-index shaft. These can flex and break if you try to force turret by hand at the wrong time. I broke one when I was first using my press, until I got used to how it worked. Lee sent me a few more free, and you can also but them for $2 at Midway. Might be worth it to pick up an extra or two.
The optional auto priming system ("Safety Prime") is probably the biggest bone of contention for some people. Fiddly little plastic parts that work OK, but need more attention than some are willing to give, apparently. I've been pretty lucky with mine, but you hear a lot of complaints about this from other (ex?) Lee owners. You really are probably better off using a hand priming tool, but then you need to adjust how you utilize the press. It's handy to be able to deprime and reprime a shell in one down-up operation vs. deprime a bunch, prime them with the hand primer, then remember to skip the flare/deprime die on the turret...
Even in indexed operation, this is not a progressive press, BTW. A true progressive does 3-5 operations at one time, and you get a finished cartridge with each pull of the lever.

P.S. ETA: I like the RCBS shell trimmer. Nice and simple.
Not sure what to make of the "floating turret" idea above. Sounds like it could be an issue, but I've never had a problem with it. My OAL is consistent across all rounds.
