I bought this one and it works exactly as expected. My mother used it recently and mentioned she liked it better than her cheaper one.
ATK likes the Nesco VS-12. Looks like the price fluctuates, try using camelcamelcamel, if you can wait. I got it with it was only $83.

I bought it and have been happy with it. I mostly seal meats and cheeses as well. You can use any bags that are no wider than 11". I've used generic bags from Amazon, Costco bags, and FoodSaver brand bags.
