Honestly if you're going for cheap, get a battery powered compressor and airbrush combo on Amazon. Get one with the hose attachment and you can use it with other airbrushes later on if you buy more. Something like this or like this, they're all the same Chinese made compressor. Don't buy from spray gunner, they resell the same thing as these Amazon shops and take the extra cups out of the regular airbrush style kit. I got one similar to the first link and it works pretty well, not as nice as my Badger Krome but well enough and I can paint inside with much less setup.
