Check this out! Found this as I was browsing the web the other day. A bit expensive at around $1200 but only $400 more then the $800 large Stainless Tumbler set up. Sure you still got to by the media but..... probably one step up from a cement mixer although a cement mixer is probably cheaper....
Check out the video at the bottom of the link too.
