I -just- got the breech lock classic cast. I looked at the rock chucker and the regular classic cast, and said and done $125 for the breech lock was hard to pass up.
It's a good press, it really is. The quick change bushings are fine, but on dies where I have minute tolerances I spent a bit extra and got a few of the challenger locks that secure with a nut.
The Lee auto prime is -okay- once you get the hang of it, I find that it mounts on the same side as I have the pull handle so it's a bit awkward.
I went with redding carbide dies instead of the lee ones, they were more expensive, but rated better, they work great in the press. I did get the lee universal decapping die, and it works fine, just make sure the brass you pick up from the range doesn't have those funky primer holes lol.

Everyone has their own opinion on them, and really, they almost all work really well. My only -real- complaint about the lee is the casting mess around the primer discard hole is insanely bumpy (at least it was on mine). I ground it out smooth and put a bevel to the hole, the primers go down the tube a lot easier now. Have fun, reloading is a blast! (sorry bad pun).
