Does anyone know about or use one of these? Ive thought about them many times, but I don't think I have a supply of enough fuel for them and I'd probably only use for the garage. If I had an inexpensive way of DIYing one I'd consider it though...
Anyway, the reason I brought it up is because I saw an ad on the site for a company that makes them. I checked it out and it looks more complicated than I expected. They require hooking up to an air compressor?

I tried to find a price on their smaller units, but was unsuccessful.
