Dand,
I don't know if I can provide any advice, but I can second what you've observed with the FoodSaver brands. I bought the basic model in 2003 (about $110 then) and was fairly happy with it. Over four years it sealed 4 elk, ~12 deer, several antelope, many pheasants / ducks, fish, and a bison this past winter. My buddies always told me the vacuum pump seemed to go out on the "cheaper" models after a few years. Not having any previous experience with vacuum sealers, I was happy getting that much use out of mine (thinking in the back of my mind the pump would go someday). But I did notice the past few critters I sealed with it that some packages weren't sealing as tight as they use to. This past Christmas my wife bought me a FoodSaver GameSaver Pro model as I was about to cut up that bison. However, it malfunctioned right out of the box, so I used my old model. After calling customer support I thought I had the problem fixed, until we wanted to use it again for halibut a few weeks ago. Same problem again. $200 for a vacuum sealer and I haven't been able to use it yet. I'm about to send it in and get my money back. I know what you're saying, for the money these things run you expect them to last awhile. Maybe someone else has experience with different brands.
