I was shopping around for the grinder attachment for the KA mixer and decided to go with a stand-alone grinder. #12 1/2 hp grinders are at Northern Tool and Harbor Freight (on sale often at $99 &$60 respectively). Figured I'd save any problems using the mixer and the stand-alone does handle the meat a lot faster, as a bonus they come with the stuffer attachment and 3 plates.
Not the best quality grinder but it will do for now.
Made 2 batches of sausage, and now the experimenting begins and a coarse grind on the beef makes a better chili
