Does anyone out there presently have and use the grain mill attachment for
their kitchen aid mixer?  How well does it grind the grain ( coarse-
medium- fine? )
How much ( pounds/KG) can you grind in one hour?

I'm looking at mills and this is an option for me.  Any info would be
greatly appreciated.

P S anyone got a grain mill attachment they want to sell?
