I had good luck with Badger's. Less with Paasche. I do have 2 Iwata's, a Revolution CR and an Eclipse HP-BC, but tend to use the Badger more.
I have a 100 G (dual action, gravity feed); 150 (dual action, bottom feed) and 200 (single action) in both bottom feed and gravity feed. I tend to use the single action more. That's probably because I started out with single action, and used it for years before getting a dual action
