I hava Iwata! - And I love it. The HP-CS to be exact. I've only had it a couple of months, but as I use it more, the more I like it. So easy to just put a few drops of paint in that gravity feed cup and shoot just the smallest of parts without wasting paint. Also amazing how little paint it takes to spray an entire aircraft.
I also have a Badger 200 that I used to fall back on when I felt intimidated by the DA of the Iwata, but now I just pick up the Iwa with no fear. Clean up is just so simple, too.
Don't get me wrong, there are a lot of other brands out there that other modellers, (with far more experience and expertise than I will ever achieve -MikeV, et al, take a bow) suggest, and you should definitely listen to their input. In fact, I'm tempted to try a T&C just to see if I might like it better, but for now, I'm happy.
