It never hurts to look at craigslist for compressors. Look for airbrush or airbrush tanning compressors. I picked up one in Addison when I was living up there, an older Badger unit for $200. It has seen some use, but it maybe as loud as a refrigerator when it starts up and fills the on board tank. Works great, and allows me to use it in my hobby room/office.
