I looked at those, but backed off when you consider you're stuck with two hoses, one pressure supply, the other relief.
However, I did buy the All-Around Jerky Maker they also sell. So many adapter plates, there shouldn't be a stuffer out there it won't fit. I've used it once for 6 1/2 lbs of raw jerky mix attached to a 15 lb vertical stuffer. When you get to the bottom of the tank, you have to take the unformed jerky out and stick it in something similar to a jerky gun to finish forming it. Not a big thing I guess. Not a bad, "it'll work for now", tool. The one caveat is that the whole process is it's a two person job (if you want to do it easily).
