Anyody with a foodsaver ever used any different type of bags with it. I.E other than FoodSaver brand Bags?

Are there any bags out there that are just as good for less money?

I love the foodsaver system and deer season, for me, is about to start. I am hoping to have a big flop eared doe down in the next couple of weeks and I'm out of bags. Just wanted to stock up, but the Foodsaver bags are pretty pricey. Hate to waste money on the knock off bags if they aint no good.
