I wouldn't buy anything but a Foodsaver. I've owned three FoodSavers for over 20 years and had problems with only one and that was because of lack of use.
Just make sure the one you buy shuts off automatically when the bag is sealed (I think most if the new ones do). The first FoodSaver I had didn't do this and you had to time it just right - not long enough it didn't seal and too long it melted the seam. Which is pretty much why I stop using it. But like I said, I think most of the new ones don't have this problem.
The other reason I would recommend them is I once bought some of their canisters (and yes, they're as expensive as hell) and didn't happen to use one for months after I bought it. Well, come to find out it was cracked on the bottom and wouldn't seal. I called FoodSaver and they replace the canister (and the lid which there was nothing wrong with) without question and for no cost - no even shipping!! First rate service.
Just my $0.02 - good luck.
