I love my Foodsaver! I have a pretty cheap one, no bells or whistles, I think it got it at Kohl's or JC Penney. I really only use it for freezing meat. Since it's just me, even a small package of meat is too much. I ended up buying a small freestanding freezer so I had room to store all my vacuum packed meat!
I suggest buying the premade bags. You can buy a roll of bag material cheaper, and make your own bags, but the seal doesn't hold as well as the ready-made bags. The bags are washable and reusable - they last a long time.
