I have an rcBS, it is fine. My problem with it is time for set-up. You have to case to use as a standard, or length guide in setting it up. Otherwise you are doing trial and error for 20 min.

I buy Lee trimmers. No adjusting, no fiddling with, just trim.

Buy a length guage for each case, and there you go.

The lathe type(rcbs, redding, etc) are great if you are making cases out of something else, and have to trim the SHYTE of a case. For day to day reloading and trimming, the Lee is SO stinking simple.
