+1 on the 2 roller for $88 or something like that. Get the one that adjusts on both ends. I picked one up and it is great. If you want to motorize other than a drill, look into the 1/2 inch shaft upgrade. Monster mills are similar, and are a spin-off of crankandstein. I am sure they are just as good. I built a hopper and base that was inspired by slobrewer's design:

Crushing your own base malts lowers cost significantly. Now if I could just get a decent harvest off of my hop vines, I will have succeeded in the unthinkable, drinking good beer cheaply. Life will be good.
