I just got back to my computer after a few meetings and saw your question relating to our food saver.
I like it so far - DH is the one that uses it but I haven't heard him complain too much. The food stays pretty good - though it never stays too long in our house!
We actually got it for free as DH's coworker got a new one and gave us his old one. But I think it works better than a normal freezer bag.
