Kopykake Airmaster compressor and airbrush, adjustable 0-30psi. Bought this years back on craigslist and I've never used since. Plug it in and it runs fine.
Lots of food-grade dyes come with it for free: I'd check for their shelf-life before using them, but for all I know they might still be good. Take them with the airbrush and dispose of them yourself if you like.
