I've had a FoodSaver for about 10 years now and I wouldn't be without it. This is probably one of the best on the market. Costco has a "package deal" where you buy the unit complete with a couple of other items like canisters, etc. They also come with rolls of wrap. This will be one of the most used items in your kitchen. I NEVER put meat, fish, sausages etc. in my freezer without vacuum sealing it first. When you take the item out of the freezer 8 or 9 months later, it looks and tastes exactly like it did the day you bought it. I tried a couple of other brands of sealers and took them back. The FoodSaver is a keeper in my opinion.
Just a tip, when you buy it pop the extra few buck for one that has a cutter. You won't be sorry.
