I use(d) the Ziplock brand vacuum bag setup. It's really pretty inexpensive for what it provides in food savings. They have a handful of bag sizes, and they're all made well enough to be washed and reused over and over. The hand pump seemed a little flimsy at first, but hasn't let me down yet during the year+ that I've had it, and when you get down to it, it really does work very well. Little cost, little effort=big results and big savings! (especially when you start doing things like buying multiple pounds of hamburger and splitting it up in one pound bags before tossing it in the freezer!)
