Check out the Aztek airbrushes too. They have interchangeable tip/needle assemblies that let you change spray patterns (and maybe colours) quickly. I'm pretty happy with mine, but can't say how it compares to others. With compressors, be sure to get one with a pressure regulator valve and moisture trap. Its also advisable to have a long hose (~2m) and another water trap before the airbrush to cool the air and trap any condensation before it hits your brush and ruins your paint work.

And Tamiya tape is great too. Won't lift off paint or leave residue like normal masking tape. Tamiya or Gunze Sangyo acrylic paints are good to work with, they spray well over a wide range of air pressures and paint/thinner ratios. I usually thin 1:1 and spray at about 20 psi.
