glad it seems to be working better, like mentioned a decent compressor will be better when you choose to get your own.
I personally like Iwata airbrushes but there a touch expensive and probably dont need anything quite so good for spraying bodies.
but for a decent budget buy I would contact Jon at RCS I believe he has a couple of airbrushes that he sells and I'm sure he could recommend one to you. He also sells paint masking, stencils etc.
I bought my compressor from Machine mart a few years ago for about £90 i think, not so quiet but does the job. you will also need moister trap and air hose.
Post some pics of the bodies you've done when your finished.
