Sarana
We have both a grinder and a stuffer. Both belonged to my Dad. Both are large, very heavy and probably professional grade. I have not researched the grinder but the stuffer is a cast iron hand crank dating from the 1940's/50's.
We use them enough to justify having them. It is a messy process and takes a little practice, especially the stuffing part.
In addition to
medtran49 I am pretty sure that
The Late Night Gourmet has one. Probably several others are well. You should be able to get lots of advice on makes and models.
George hunts so we use it to make venison sausage and ground meat. G picks up pork shoulder roast when he finds them on sale (.99 per lb) . We make fresh pork sausage. Last year we experimented with Italian sausage
Once you get the hang of your machine the fun part is trying out different ways to season the sausage and ground meat. George likes to make venison/pork breakfast sausage patties.
Good luck with your quest.
