Iwata Revolution TR-2 Airbrush?

I have the Kustom TR. The difference between the two is the paint feed. But its the same trigger configuration. This airbrush is best for longer spraying. As it have an ergonamic feel to it. So I make this as my main workhorse.

 And here's another link for more detailed review....

I would agree with the statement about 'long' painting times.  You *will* fatigue over time; when I've done projects spanning hours (i.e. multiple models, terrain, other projects) having 'pistol grip' configurations on sprayguns and airbrushes is a life saver.  I use a G6 for larger work, and like it.  I've thought of trying others, even non-name brand brushes so I could have them for certain work.
