I started many years ago with an hand crank #32 converted to electric pulley driven. It worked ok, though a little dangerous with the exposed parts. Then about 12 years ago I converted another #32with and industial right angle drive and 2 hp motor. This one worked ok too but was a bear to handle, it is heavy and cumbersome. I recently purchased this Cabela's # 32 and it's grinds very well and it's made where you can attach other things to it. Here is a picture I took while making up a small batch of summer sausage. You can really see the leaness of the venison on the left. So far I am pleased with the Cablea's equipment, I see it money well spent if you want good quality and to last a long time.
Here is a mixer attachment for the motor unit, it makes it a snap.
