I have
this Foodsaver branded vacuum sealer. I bought it at Costco for about $100 (as a Costco bundle it came with a bunch of bags and bag storage/cutter thing). It's about 5 years old now and it works just fine. I couldn't tell the difference between the fancier models and this one. It also seals '
Foodsaver' canisters where I store pasta and dried beans/lentils.
As a side note, I read the reviews from the link and haven't had any of the issues those people are experiencing with the canisters.
