I was checking these out the other day and thought it would be great for guys that get the butch to do their ground and want to try making sausages on their own, it hooks to your sink tap and uses water pressure to stuff the casings..

On another note, I was talking to a buddy of mine whos mother use to make sausage as a kid. She apperently made a stuffer from a plastic 2 liter pop bottle & an old funnel. She cut the bottem off of the bottle. Cut the tip off the funnel & the center out of an old cap apprently work quite well...
