I don't have one of these so take this for what it's worth. I've always wanted one too, but what's always kept me from getting one is knowing that the bags are so expensive. I've heard around 50 cents per average sized bag use. That may or may not be correct. I know people that have them and do like them--especially for fresh fish after fishing. But I don't know if I'd use it for every day use because of the price of the bags. Probably just for meat for longer term freezer storage. Also, they make many different models of these things with big price differences, so you might want to look at several to see what the differences are. If anyone that has one can comment on the differences, it would be helpful.
