My first touch up sprayer was a husky. I think I paid $50 for it. Worked like a charm. The iwata ones are a little more expensive but they spray a lot cleaner.

As for the airbrush. I love my dual action iwata. A lot of the detail on the necromac came out o that thing. Once I finally broke down and bought one, I was kicking myself for not ever having done it sooner!
