WOW! You do have a lot of jerky. Regarding the vacuum sealers, I have bought high dollar and mid range to use and have found that they all wear out about the same time, so have not bought a very expensive one again. They all last me a bout three or four years and I have worn our several. BTW, I am Rutabaga's wife. I use my sealers LOTS! I garden big and put lots in the freezer. After they have been used for a few years, as least the way I use them, they begin to not seal as well. They just simply wear out as most appliances these days. Good luck with all that jerky.
