My compressor is Home Depots cheapest, a three gallon Husky. It will blast air fast and long enough to see if you can get a bead to catch without wanting to chop up the whole bike.
While tubeless tires are nice anywhere, you have to experience a goathead patch to fully appreciate them. We're talking 15 flats a day. I had a Geax Saguaro which had been poked full of holes on the New Mexico section of the Great Divide, so many goatheads we had to leave them in because the thorns were plugging the leaks. I made that tire tubeless, and all the pinholes spurted Stan's sealant for a second, then stopped. We rode in the cactus country of the Arizona Trail with that tire without a flat.
Here's a youtube on how to make a tire tubeless. There are many others, if you get tired of stupid pet tricks and moose tramplings:http://www.youtube.com/watch?v=3Q--iWFpTjg
