I ended up going with a crankenstein Mill, but wanted to motorize this permanently. Since my Apartment is relatively small I needed it to store really compact. So this mill I made stores upsidedown inside of a 5 gallon bucket; is powered by a AC gearmotor and can hold 8 lbs of grain in the hopper
I've some more photos on the webpage here along with other projects and documentation of my semi-automated setup

Note: Since taking these photos; I swapped to a chain drive to power the mill as my belt drive kept slipping (diameters were just too small for the torque required)
