I like this little Kitchen Mill.
It will grind grain, corn, and beans. It does a great job!
It is a heavy duty little guy that can stand up to lots of abuse and has been used by many of my commercial bread making customers.

(This is the one my 3 boys put BB's in to make an exciting day of sparks flying... and no it did not survive this!)

It has a small hopper on top that has to be re-filled to get enough flour in the pan to make a large batch of bread, and it is the loudest of the electric mills, but it should last a lifetime!
