This'll do for touch ups... 0.3mm nozzle.. by pushing the needle all the way forward or by pulling it back slightly you can get lots of paint flow or very little. Also big enough to allow acrylic to flow OK.

Any of the $60 compressors will do the trick also.

This one seems exceptional value:

Youll also need one of these which regulates the air rate at the brush end... if air rate is too high then paint just goes splat on your work.. this tool gives nice fine tuning..

Most of my airbrushes are under $50 from Ebay... all work well, but if you want to go top quality then look at Paasche or Iwata brands
