I use the Thumlers Tumbler A-R12. It works really good and has great quality. The bin is sturdy rubber so it is quite quiet. http://www.amazon.com/Tru-square-Metal-Products-130-Tumbler/dp/B000BUUT6E You may be able to find it cheaper if you search online. This tumble is quite large also. There have only been a couple of long pieces I could not fit.
