This guy builds larger tumblers. The largest will do 2500 9mm cases. I am going to build my own. Sourcing my parts from ebay and local shops, I can do it for myself for about a third of the cost of what he wants. I won't build one for anyone else as that would not be ethical of me.
I do have a Thumblers model B tumbler and it does do an awesome job, but is a pain in the rear to do only a few hundred at a time. The pins are neccesary to get the shine. The lemishine really only softens the water and allows the dish soap to do a better job.
