I have been building plastic models (the real kind that you actually have a part in making ) for about two years now. I have never really been that happy w/ paintbrush results. I am trying to step up the quality of my models from very poor to somewhat OK. I am looking for an airbrush and air source for plastic models. I don't wan't it to break the bank, so please, no combo over $250. If any of you have had good luck w/ a certain airbrush, air-source, or both, please let me know. Thanks a lot!
