Not to hi-jack a thread but I recently bought the new Frankford Arsenal Rotary tumbler and have been very pleased with the results. Not normally a fan of most products from Frankford Arsenal but this tumbler is very nice. It comes with the SS media, has a timer built in, and seems well built. I can get about 1300-1400 .40s cases at a time and I have done about 900-1000 300 blackout cases at a time.
