I got a great Foodsaver for a lot less than the one you're looking at. It holds 11" roles of bags. Has a tube for removing air from canisters and bottles(for saving wine for example). It's great. Take a look:
T000-18004-001 FOODSAVER® V3840
The kit also comes with one role for making bags and an assortment of bags.
I find it very handy.
