You can pay more, but why would you. This Chamber Vacuum has everything you need. It has a very strong seal bar - very impressive vacuum ability - and allows a very decent size bag for all your sealing needs.
I have been using a food saver for years and gone through many of them. The food saver bags are expensive and you can't vacuum anything that has a lot of liquid. The first thing I sealed with this Chamber Vacuum was a bag of water (worked great). The bags cost about 80% less then food saver bags, and you can buy bags in any size. This DZ260-C easily vacuum sealed a bag that was 12x14, I personally don't need a bag any bigger.
