I looked at CT and PA and they have compressors from $60 for a small tank and about $100 for a bigger unit;
Powermate 1 Gallon Portable Air Compressor | Princess Auto
so if I bought the dual air gun and cheapie compressor I could be into airbrushing for about $100 to test it out.
I am fairly artistic and good with a hand brush, just curious about airbrushing and how it woks on paper models. My thinking is the airbrush would be better for finer detail and accuracy, as my eyes and finger dexterity are not as good as they used to be.
