Welcome to the forums, Mortarman! I look forward to seeing your builds.
And regarding the airbrush, I can sympathize. I started using one, after thinking about it for years. I still have a way to go, but I can tell you, you can really improve your game with it. The key is to practice, practice, practice! Also, don't be afraid to spend money on a good brush. The money is well-spent, if you get a quality tool that lasts a long time and gives you good service.
Best regards,
Brad
