Foodsaver is a great unit and bags are relatively inexpensive an easy to come by. (Wal-Mart etc.) One word of advice tho. It you buy one off E-Bay altho you can get some good deal's on new one's there. Foodsaver will not honor there warranty on there product with a receipt from the seller from E-Bay. It has to be bought from one of there recognized retailers. I had a problem with one of the new one's I bought off there. Sent the warranty card in and all, and they wouldn't take care of it. Great unit's tho. Have several I've bought for family, friends and myself and they work great.
