You'll really like the Valley mill, and Catt22 gives good advice on the settings. I've used 1 for years with no issues. Squirt a tiny bit of Dupont dry wax spray (or something similar) on the outside ends of the bearings to keep them from heating up and squealing. Use a brush to keep it clean, away from your fermentation area of course. I made a pvc pipe stand for it, and added a motor. Happy crushing!
Oh yeah, Valley is gone, and they never published actual numbers for the clicks.
