I have this one (or one that looks just like it). I stole it from my wife's craft stuff. She used it for years before I took it. Works great for shrink wrap. I was using it for my film-free waterslide decals, too, but it gets too hot for that so I switched back to the hair dryer (the heat gun was setting the toner as if it were in the oven, not giving me a chance to clean up before baking). So it puts out a good amount of heat, too.
