I was at a Target store today in Denver and found that they had put their air compressors on clearance. I picked one up for $44.98 (original price $89)! This compressor has a max pressure of 100 psi and a 2 gallon tank. Two gauges display the tank pressure and the regulator pressure. Included are a hose, a tire filler nozzle, and a blower nozzle. All I needed was a $1.50 1/4" brass nipple to attach my airbrush. This unit works like a charm! More info about this compressor can be found at:
