I had a food saver for years and while it worked ok, sometimes getting a seal and keeping one was a problem.
After reading the advice here I ordered the Vacmaster Pro 260, but when it arrived it was DOA. My wife was also not happy about how large it was, since we leave ours on our counter top.
So I ordered the Vacmaster Pro 140 and so far I am really happy with the results. Also I like that it has a double seal unlike the Food Saver line.
