We bought a Italian made "vacupack deluxe" after much reading. It isn't cheap, but we wanted long term value. It has a rebuildable pump and can handle liquids better than most. We have used ours for 3 years and it has been great.

We considered the Weston for the same price nearly, but took the longer warranty.
