I got a craftsman compressor from sears for $300 a couple years ago. 6hp 30 gallon tank. Works great. I use it for my impact and air rachet all the time, I also use it to paint. It's a little slow for painting a whole car, but overall I'm happy with it. I would go to sears or home depot and see what they have to offer. You can get one that will do what you need for under $500.
