I was given a CTire grinder (Waring?) for a present a while back, but it had issues from the too late to do anything about it outset, as I had it for well past the warranty period before I tried to run any serious load through it.
I may have just finally beat to death my Princess Auto grinder that came from a garage sale for $5. It sounded like it had rocks in the gears from day one, but worked like a trooper until I stuffed a nearly complete lower leg tendon bundle into it, and stopped it. It eventually ran again, but it clicks...
But a bud dropped off a #22 size unit that was at his place when he moved in. Took two folks to put it on to the kitchen counter, damn near killed me getting out of the way and down the stairs! Heavy pig! Not cheapskates with the cast iron when they built it!
Figure I will rewire it from 220V to 110V (dual voltage motor) and buy a new knife and plate for it, as the knife seems OK, but the plate looks fine enough to make bologna with.
I figure that a fellow that wanted to save some coin would be best to be looking at the Number 32 hand crank type units that can be easily motorized with a couple pulleys. The Cabela's machines, I have not used, but am leery of the price difference between them and comparable models from the meat cutting suppliers, which seem to be running right around $1K for the size range, on up to real money.
In any case, the cardinal rule is the same. Sharp plate, sharp knife, cold meat, and tighten the cap on to hold the thing together until you think it'll break, then a little more!

It keeps the knife against the plate, thus keeping it cutting.
Kinda handy to have a wrench that fits the cap, for taking it apart afterwards!
