What the cheapest air brush I should get to paint crankbaits

A good quality start up airbrush is the Iwata Neo.

Well, the absolute cheapest is to take a 50% off coupon from Michaels or Hobby Lobby and buy a single action Badger airbrush that comes with a can of compressed air for around $15.  Air from the can shoots over a venturi nozzle connected to a little tube that sticks down in the attached paint jar.  Single action means the trigger controls only the amount of air being shot.  You control the amount of paint shot by screwing the venturi nozzle in or out of the air stream.  You can use this setup to shoot cheap hobby paints thinned with water.  Pretty crude but you did say "cheapest".

 

If you want something a little more user-friendly, buy a cheap double action airbrush and attach it to a compressor (a tool compressor is fine).  Double action means the trigger controls both the amount of air and the amount of paint being shot.  Push down for more air, pull back for more paint.  Like JeziHogg says, the Iwata Neo is a good candidate.  You might find a good used airbrush somewhere too.

This is just MHO...If you're gonna go the cheapest route for airbrushing cranks, you're probably better off just buying some new cranks from the store rather than wasting money on a cheap setup.

I am going to have to agree on this.

If you are really planning on painting your own cranks, buy a good Iwata or a brush equal to it. If you don't you are wasting your money and time. 

Anybody have a reference for a good indoor (quiet) air compressor?
