The Foodsavers requires special channel vacuum bags which are relatively expensive.
I am not sure what the Cabela's unit uses.
Might I suggest research into the Sinbo unit?
http://www.dougcare.com/foodstorage/homeequip.htm#sinboIt uses standard vacuum bags.
At the same site listed above, an 8x10 bag (bulk purchase) is
standard : 0.05 each
channel : 0.15 each
There are multiple vendors for the Sinbo sealer but as far as I can tell, all are online dealers. I have yet to see a storefront carry it.
