$30 Corona mill from Amazon, it works fine.
The one they are selling at the moment has terrible reviews but pay them no mind, it's actually pretty well built for 30 bucks. People say it smells like oil, and all these other crazy things. It smells like coal out of the box, probably because of the manufacturing process.
The only real complaint I have about mine, besides the manual labor involved, is it tends to throw some excess grain on the floor, for 10 lbs you lose about 4-6 ounces maybe.
You can connect a drill to one, my cordless wasn't quite powerful enough to run mine.
