Half of the battle is finding the right paint. In a lot of cases,the paint being used is of more import than the airbrush. ( as near as I can tell,as long as you aren't using the mondo-cheapo Chinese slave labor produced ones,airbrushes are honestly pretty generic.)
I finally discovered 1-Shot(sp?) brand paint,and there are probably other equivalent paint brands out there,if you do some research. It's made for sign painters and other grapic artist types,and has a lot of pigment. I did a test-Rustoleum black vs. 1-Shot black,equal amounts of paint in jars filled the rest of the way with thinner. The 1-Shot,although much more expensive-looked to have almost twice as much pigment as the Rustoleum. So,to an extent,you get more for your money.
And you also get a wide variety of colors. Almost automotive colors,but without the hassle of large quantities,hardeners,reducers,etc. It's just plain old paint that can be thinned and cleaned up with mineral spirits.
