Opihi,
I've been using my RCBS tumbler (forget the model#) going on 11yrs. I highly recommend it. Its a little more "heavier duty" than the Midway models (I do have 1 and it works fine). Only problem in all these yrs is the motor burned out 4-5 yrs ago, which RCBS replaced free- lifetime warranty!
No experience with the Dillons or who makes their tumblers. I do know its
not Lyman... 3 guesses what the
FL stands for in front of Dillons models.
