I have two Aztec airbrushes-they have nice models too! And don't forget if you have a Michaels or A C Moore near you a 40% and sometimes 50% coupon is usually available every week. That's how I got my airbrushes and the 'blue' Aztec compressor. Really a sweet deal.
They also carry the Createx lines of paint which are already at the right mixture for airbrushes. Lots of cool colors, pearls, fluorescents, metallics.

Also my AC Moores now carries rockets, they've sub-leased space for hobby stuff. Now expanded plastic model, rocket, and train sets.
