I have a maltmill, just set it up with a 5 gallon water jug hopper and cobbled together something to make it sit securely on a bucket, it is powered by a harbor freight drill. It is a beast. the mill gives a great crush, I have also used a little beauty called a Phil Mill, a single roller deal. once modified to have a larger hopper size it was a joy to use. I paid 50 bucks for it, just sold it on here recently. I can wholeheartedly recommend both the phil mill(which is sadly no longer manufactured, and the schmidling malt mill.
