If you want to save some money, here are my suggestions.
Airbrush: Paasche H Simple, cheap and does a great job. About $40 to $60
Compressor: Go to Harbor Freight and buy a decent one for around $100. While there, pick up their airbrush cleaner brush set and their spray out pot. Look for coupons.
For cleaning, I use lacquer thinner (Walmart, 1 gallon about $15) for lacquers and enamels or 91% isopropyl alcohol (Walmart, about $3) for acrylics.
You'll need to decide what type of paint you're going to use. If fumes are an issue, you'll probably be using acrylics. I'm using Createx right now and like it.
