Hand cranked grinders are fine but they are work.
I went with electric for the ease of use.
If you want to make a few pounds of ground beef it's the way to go.
Search Ebay and check out yard sales.
I got mine from LEM Products. It was reconditioned and cheaper then new. I think what it was is a grinder that someone didn't want and returned it so they sold it cheaper so as not to eat the loss. Works fine and I'm so happy not to have to turn that crank.
I haven't bought ground beef,turkey,or pork since I got it.
I also know what's in the product and a rare burger isn't something I worry about these days.
Good luck in your search.
