I'm a low volume shooter and I use my Lyman1200 wobbler/vibrator. I've had it for about 8 years and it's still working fine. I do about 100 rifle cases or mebbe 150 handgun cases at a time with corn cob blast media and plastic chip mix. I only paid $40.00 or so and I think if one needs cleaned/polished brass, the Lyman will do the job...
I've experimented with home made rotary tumblers, have a HF rotary for tools, parts, and brass, but the Lyman works OK...
(BTW; I couldn't boycott L.A. as they gave me a paycheck every two weeks for 25 years)
