It depends on what are you doing with it. For a relative simple external mix single action airbrush you can get from art supply store and it works good enough to start off with. Art supply store also sells a very nice double action airbrush with 0.73mm nozle for under $64. These seem to work very well and it can be set to do extremely thin fine work.Hi there every one!!! can anyone tell me from where I can buy a good quality airbrush? I need the airbrush gun and compressor both for bike and helmet paint. Not sure what is a good prize to pay...
