Interesting topic... I've learned a little from it, thanks for sharing your research. I've seen the turbine stuff advertised but never actually seen one in operation. I know a couple guys who do custom paint work but they use conventional stuff... turbine seems better, wonder why they resist it?

, what's the deal?
The first thing I think of when Wagner is mentioned are those hideous things they sell for house painting. Makes a godawful racket and will vibrate your hand numb in seconds...
