I have an old electric american made grinder that i bought in the 70's, i've made a LOT of sausage with it since then! IF, i was buying a new grinder today, i'd buy the 1hp one from Cabela's. I believe they are made in Italy...
My brother makes a LOT of sausage/brats and after seeing how nice his 1hp model from Cabela's has been working for him, i think it's worth the money. Another thing, Cabela's will stand behind their product, that's worth something to me right there.
I would NOT buy a hand turn grinder, i have a couple of those and i wouldn't want to have to go back to them! PEROID!
I bought a grinder for the Kitchenaide stand mixer, and it does grind, but it's slow, rather sloppy made and looks like a pretty low quality product to me!
Buy a GOOD grinder and if you want to keep makeing sausage, buy a sausage stuffer!
