My wife bought me the Cabela's unit ($400 I think) for my birthday, and I am very happy so far. The big seal strip is fool proof. The other thing I like is the size of the seal bar. I can seal two bags at the same time which greatly speeds up the processing time. The bags it uses have a mesh layer inside that is different than the Foodsaver bags. I purchased a grip of pre-made bags, no more cutting bags out of the roll for me.

I've still got my old Costco foodsaver and a bunch of bags, if you want it make me an offer...
