I have the Food Saver Proffesional II. It is about 4 years old and quite frankly does not work like it once did. I now have to manually operate it and it just does not suck out the air as good as it used to. Does anyone have commercial sealer that is advertised in Cabela's? It is a stainless version and cost about $150 more then the foodsavers. Looking for any feedback on this unit good bad or otherwise.
