Thinking this could go into either this category or the equipment category, but will try here first as roasters are the folks who use them.

I am interested in a small batch destoner for a retail roasting environment.  Seems all I can find on the market are for much higher volume environments.  Anyone know if there is a producer of such a unit? 

If not, I might have a machine shop fabricate one for me and I could probably negotiate a much better price if I were to order more than one unit, so is anyone else interested in such an item (probably built to handle 2-3 kilo's)?
