If you want a fairly good one for home use Northern Tool sells one. The meat mixer is great to stir it up before grinding to distribute the seasoning and not having to grind in once and add seasoning and grind again. I've had mine for 4-5 years and use it every deer season and stands up OK and sure grinds it up fast.
I have same. Kitchener #12. Have had it 4-5 years and do 50 lbs per year. Has 3 plates and sausage stuffers. $80 with $20 coupon. One year I made 60 lbs of sausage. No problems. If I do not cut fat up small enough I have had the front pop off if not tight. Only problem. Best for money. Used hand crank for 25 years. Hand not bad with 2 people or son with guns. I shoot 4 - 5 deer per year so the Kitchener had paid for itself many times over.
