I use one, but I tend to use it more for freezing produce, as opposed to cooked meals. With juicy stuff, it's a little annoying - you need to use a paper towel, or pre-freeze it and then vacuum seal it. That works pretty well, actually. What I've done before is make 3-4 pans of enchiladas, freeze them in the pan (inside aluminum foil), then pop them out and vacuum seal them for longer term storage. I did that when I was expecting a baby, and it worked perfectly! I took out enchiladas months later and they were good as new.
