I too have a harbor fright air brush, paid $15 for it. mine is the dual action internal mix gravity fed version (and I love it, although there are much better ones out there, you get what you pay for)

you should look at pawn shops for air compressors, they are usually quite cheap, and most pawn shops will have them.

or go to a welding supply store and rent a tank of compressed CO2. you might have to put a sizeable amount down for the deposit, to cover the cost of the bottle if you don't bring it back. the CO2 will have about 300psi, and will last an average person about 3-5 months of normal airbrush use.

another option is to get an air tank and fill it at a gas station which uses a compressor that will fill over 100 psi. this will last about 1/2 hour depending on the size of tank you get

hope this helps....

oh and look at harborfreight.com for a small compressor, their prices are usually much cheaper than the store itself,
