I am thinking about getting a vacuum sealer. I would like one to freeze things like jerky, fresh caught fish, steaks, etc. My grandpa will sometimes get a rib roll, age it, then vacuum seal it for everyone. I am not sure if he is doing it wrong or if the machine he uses isn't very good. By the time I am ready to eat it, the bag is all loose and has ice inside. I would like to buy one that isn't too big or too expensive but also not some cheaply made, couple of use, type machine. Any help is greatly appreciated.
