fishstix...I am no expert on who makes a good chamber machine. I just am lucky to have inherited a $5,000 commercial machine made in Switzerland. It is huge and weighs about 250#...There is a place on Rainier Ave that sells bags and both types of machines. Every year at the fishing shows I have seen someone showing a nice one. They are so slick you will laugh at the Foodsaver by comparison. Price is a problem. Check out the dougcare.com website for lots of info. Look in the phone book..best I can do.
