I have quite a few airbrushes, Harder Steenbeck, Badger and Iwata.
I am an Iwata guy, but with that said, the Badger Renegade Krome i have is an awesome airbrush, it sprays fantastic is very responsive and i think it performs just as good as the 2 Iwata's i have (HighLine C-Plus and Custom Micron C plus).
Just one thing i found is that the finish is not the best i have seen, the inside of the cup is not that smooth especially at the bottom, making it very hard to clean as the paint is having to many places to stick to.
The Harder Steenbeck's is the Ultra (great beginner airbrush) and the infinity also great but i just can get along with it so that is getting sold pretty soon.
Havent tried the Badger Customer service, but only heard great stuff about them, and usually you will hear only the bad if any.
