I have at least 5-7 of those Foodsavers. They're like $100 new, but I got mine at Goodwill for less then $5 each. I keep an eye out for them. I used one about a week ago. My Mom bought a big bag of coffee at Sam's club, and I resealed it in a bunch of smaller bags to keep it fresh for her.

If you didn't know, you can buy Walmart brand vacuum bags for like 1/3 the price of Foodsaver brand bags.
