Apparently some people just can't read. The Aztek airbrush is NOT marketed as a 'professional' airbrush such as one used by photo retouching specialists, airbrush artists or the like. Look here (again): http://www.testors.com/brand_profile.asp?brandNbr=1
It is clearly marketed for the "EXPERIENCED HOBBYIST".
Also, please understand, I have never said the Aztek A470 was superior to any other airbrush mentioned so far. But I firmly believe, for most modelers, the A470 is a exceptional airbrush able to perform all the requirements for model building. Remember, this is a modeling forum, not a forum for T-Shirt artist or people who make paintings and the such. I've looked at Mike's website and his work is outstanding. If I was using my airbrush for more then making models I won't use an A470 either. You know, use the right tool for the right job.
The point is, this is a forum about making models. The Aztek line of airbrushes are excellent for that. These are airbrushes designed and sold by a company who specializes in models and that is what the airbrush is marketed for.
