I have one dozen industrial grade Hobart coffee grinders. The local Krogers' stores used to use them for their 'grind it yourself' coffee service. I found them abandoned in a warehouse for salvage price- VBG :-) 'Course not all of them work, but it only takes one & I figure I have spare parts now. I also picked up 2 peanut butter grinders but haven't tried them yet. -Jim C MWPH
