I'm actually on the cusp of getting a crusher too, and would like the same questions answered. I like the price of the Barley Crusher, but need to know if the 2 roller Monster Mill is worth the extra money (it's about $50 more to get it set up almost the same, with hopper and base)... I'd rather spend less, but if there's a large enough difference in quality, then I'll spend what it takes.
I'm about to have close to 400# of grain on hand, which I expect to go through most of within 12 months... So I'll need something that can stand up to that much use (every 2 weeks, BREW DAY!)...
I'll probably be connecting my cordless drill to it (1/2" chuck 18v DeWalt), but having a hand crank is a good option (just in case)...
Also, do I really NEED the larger rollers (2") or will the 1.5" do the job for home brewing? I'm not going to be milling grain for the entire region after all. I am pretty sure I'll want steel rollers though, not aluminum.
