I have both a lee classic turret and a 70's RCBS RS5, and will try to make this short.
The RCBS is a great press, its been running since the 70's, lol. Longer cases can be tricky, you have to insert the bullet into the die then put it on the case mouth, takes about a minute to get used to. RCBS has the greatest customer service, doesn't matter if you backed over your press with a dozer, they'll replace it, no questions asked...but you pay for that warranty.
The Lee classic is a great press as well, but with precision stuff, I use the RS5, the classic turret is great in that you can use it as a single stage turret press, or set it up as a progressive with the auto indexing feature. I use it for handuns, and none of them know the difference according to groups. I've heard their CS is to be desired, but I've never used it either...If your loading handguns, give the factory crimp die a try, one of the best tools around IMO.
As far as digital scales go, I use a RCBS digital scale/dispenser combo. Let it warm up, check the zero and go. I usually check the zero every 15 rounds, and have yet to have it drift while in use in 10 years. Just need a good set of check weights to make sure everything is fine, and no flourecent lighting on the same circuit. A good surge protector as well that will alert you to low or high spikes.
All in all, I'd reccomend a single stage RCBS for rifle/precision work, and the lee turret for pistol rounds...and with a 1/4 turn and a shell holder change, your set for another caliber, which with handguns, I'm using 4 dies...thats alot of time wasted changing dies.
