I bought one of these over a year ago, and have been happy with it.  Here is a review I made:

Iwata power jet pro review

It is more of a compressor than I needed, but the dual set up was cheaper at the time of purchase than a single one would be. 

I mainly bought this because my daughter was using an airbrush for hours at a time and it was burning up the tankless compressor I had.    This one is rock solid and I don't think I can burn it up.
