here's a thread I submitted a few years ago on reproportioning seasonings, etc.
I use seasonings and mixes from Butcher Packer and am very satisfied with them. http://www.butcher-packer.com/
I do make up my own brines and breakfast sausage seasonings and am re-doing some mixes to lower the salt content too.
I bought the Cabela's 1 hp. grinder and the 15lb. Northern Tool stuffer and have been very happy with them; but I was in the meat business for 30+ years so I knew what to buy. However, for home use I started out with a KitchenAid grinder w/stuffing tubes and used that for several years until I could afford to buy what I wanted. It was slow but it did the job and was able to produce lots of tasty products! And, not done yet; if I get more time and money (lol) I'll go up to the 1¾ hp. Cabela's grinder and probably a 30-40lb. motorized stuffer and 40-60 lb. mixer; and remodel my garage into a processing area! Of course, that will happen only once I can afford to send the wife on non-stop cruises, lol!
