Yes I know the Westons well I researched them also. I decided to go with the Cabelas because it has the air port pull air from the top which will help When sealing bags with some moisture that may leak out. Although I really liked the look of the Weston and I wish I had the blue color on mine. The Weston was My second choice it's a great machine with great reviews as well.
By the way if you can cut a straight line I think these bags are a really great value especially for our machines.
