If you were creative enough, you could set up propane or mapp gas with a
compressed air setup instead of the small oxygen tanks. Compressed
atmospheric air is just about as good. I have a torch like this that we just
cut the hose, and attached to the air compressor....
thus giving you a limitless supply of air, and you just have to replace the
Mapp gas tanks. Heck my jewelry studio is run on compressed air and natural
gas....
It's plenty hot enough for most things, and it's just about as close as you
can get to limitless.

I still recommend the $50 homedepot setup. It's hot.
