I researched mills quite a bit before buying one earlier this year. I was heavily considering the Barley Crusher, but decided on a Monster Mill MM2. It seems to be made a bit better, though the Barley Crusher will likely work fine. For what it's worth, Fred, the guy who owns Monster is a super helpful guy.
I know satisfied owners of the Barley Crusher and the JSP Malt Mill. In the end, just about everyone seems to be pleased with whatever mill they buy, so in a way, you can't go wrong.
