All depends on the capabilities you want. I picked up a Gander Mountain Guide Series #12 meat grinder with 3 sausage stuffing nozzles, snack stick nozzle & at a super discount. It is a grinding BEAST. It will grind 11lbs of half frozen venison and pork fat in about 60 seconds. Seriously powerful. I have never even heard it bog down, no matter how fast you put things through it. It is heavy & lacks some of the features found on today's grinders but I have no issues at all. The biggest complaint that most people have is the gumming up of the fat/sinew/tendons in the auger. If you keep the meat cold, it is way less of an issue. It is no issue at all with mine. There have been a few times when I was done, upon take down for cleaning, there was some tendons/fat/sinew wrapped around part of the auger but it did not slow the machine down at all. The auger on ours had a new feature at that time, (the first half of it was farther apart to allow more consistent & faster feeding) but now i think it is standard on all commercial grade grinders, it sure works good. Motor never even changed pitch. When we were looking at them, an old timer told me to buy the biggest one I can afford because the extra power is worth it. Now at 54, I am becoming the old timer, LOL.
If I was gonna buy again (because mine is no longer available), I would go with a LEM or a Cabela's 3/4 hp #12.
