You can get an Iwata Neo airbrush for about $50 - $60 these days. Iwata airbrushes are used by prefessional artists and are considered to be among the best in the world. Check out Merlin's post most of the way down
this page (Dated Aug 10th) to see one.
You should get a compressor with an air tank if you don't want to deal with pulsations in your paint stream. You can usually get one for less than $200.- at your local hardware store. The other thing you'll need is a water trap, especially if you're going to be spraying enamels.
You'll never be completely free of brushes. They're the absolute best thing to use for touch-ups, weathering, small parts and cockpit interior detailling. You can also do some pretty amazing work with brushes. Here are some of my models that I've done. I'll jut blow the dust off them and snap a few pictures. None of these were airbushed:
Monogram Pro Modeler P-39 (yes, I know the blue circle should be under the starboard wing, but I have an excuse: I followed the instructions!)
Hasegawa Hurricane II
Hobbycraft Seafire XV
ICM Spitfire IX converted to 16
Accurate Miniatures Yak 1b

Ne Omega Yak UTI-1
Tamiya Shiden (Okay, I cheated a bit with this one, the silver is from a spray can. I painted the green overtop and just before it was fully cured I applied masking tape and ripped it up to create the chipping effect. The small chips were done with a dental probe.)
I painted these with Humbrol, Testors Model Master and Tamiya paints. The trick is to mix the paints really well and use really good quality brushes. Oh, and 20 years worth of practise doesn't hurt
