I have the same Northern Tool grinder mentioned here, have had it 4 years. I have ground up 3 elk, and about 50 deer, with zero issues. Because the spout opening is small, you have to cut it into smaller pieces. Close to frozen cold meat process's much better, as mentioned. Another great place to buy the poly bags, which I stuff with the nozzle that comes with this grinder, is The HOmeProcessor.com. He has good deals on all great quallity items, including summer sausage products. He has heavy duty grinders, cheaper than the same thing on Cabelas.
