Where can I buy an airbrush?

Where can I buy a cheap airbrush kit to see if I like airbrushing?

• Oh and also the paints? I want to see if I would like using an airbrush for painting figurines. (Games Workshop, if that matters) If, I like it or if anybody reccommends it, I will buy an expensive, fine detail airbrush. But for now, I just want a cheap kit and paint until I learn how it works and if it's for me. I think I have a compressor somewhere in my garage. It's one of those big ones my dad uses. Will that work. I can deal with the noise.

• Answer:

  You'll know when you need an air brush, they're brilliant but the only advantage is that they allow you to cover a model in much less time. Air brushes are useful for painting vehicles in 40K but most miniatures are best done with a normal brush. For much larger figurines such as resin "garage kits" an air brush is a necessary tool but I doubt you'll really need one for Warhammer miniatures.
