Mine should be here any day now, we've been saving up and ordered it just last week. We bought the Family Grain Mill, also known as the Jupiter Mill, from http://www.pleasanthillgrain.com/family_grain_mills.aspx It works both with power and by hand cranking
I can let you know how it goes, everything we read online said good things about it. We've been stocking wheat and we're really raring to bake up a batch of bread with freshly ground flour!
Warning! The cheap hand crank mills on ebay won't make rice flour. DH cranked for a long time and it was still little balls of rice. Adjusted mechanism, etc.
