Greg, I'm with Mike on this.
Double action isn't so hard to use. A few minutes time practicing on scrap will help you out a lot.
I have a 100LG and 150, both come with a pre-set screw that's supposed to allow it to work as a single action, but I find it's more difficult to set up than just practising the press and pull technique.
I also bought a Badger 200-20 single action detail brush, that allows you to dial in the spray size. I find I often just end up using the 100LG since the gravity fed color cup makes it a bit easier to clean up. I save the 200-20 for when I really need consistant lines.
Don't give up on the 360, it's a fine airbrush, and once you get over the learning curve you'll love it!
Cheers,
Bill
