I have a 7lb hopper Barley Crusher and I love it. The only thing it may take a couple of additions to crush a grain bill, but that's not a big deal. I definitely recommend buying a 1/2 inch chuck drill if you don't have one already, crushing by hand is a giant pain in the a$$. Also, it is adjustable, buy some feeler gauges to be able to set the gap, I use 30 thousandths. But use whatever works for you.
