I suppose it depends on where you live on what the price is going to be. This is what I layed out for my airbrush & compressor in Canadian dollars.
Paasche H Airbrush - single action - comes with 3 size tips - $120.00
Compressor from the local hardware store c/w regulator - $135.00
Moisture trap also from hardware store - $10.00
Total $265.00 Canadian so you should be able to get below the $200 mark in U.S. dollars if you shop around a bit. The larger compressor is nice for other household projects too.
Happy Modelling and God Bless
