Hey Roy,
Your welcome.
Well there are alot of nice Badger air brushes, and different ones for different uses as many are.
Model 100-200 are nice for models.
Model 350,250, are good for large areas.
The Badger Model 150 is a common one for alot of modelers for painting.
I my self have alot of Badger air brushes, as well as Iwata. I have a Badger 360 model that is awesome!
Some Tamiya paints are just about thin enough to spray without thinning, just check the paint before ya spray it is all.
The paint for lexan is (most of it) is pre mixed and I have also used that before too.
*For primer I only use Plastikote automotive primer for everything I do, every part etc.
When ya get the air brush i can give ya some more info. on it too. Any questions feel free to ask!
Manny
