It depends on how often you plan to use it. I usually process 2 dear a year for myself. I might only grind 20-30 pounds of that meat. So I bought a someone cheap unit from Bass Pro, around $125.00, or something about 10 years ago. It has worked fine. If I was at a deer camp and grinding hundreds of pounds at a time I would obviously want a higher end model. I too see no reason to ever be grinding bones.......
