David, unfortunately there is no "best choice". An airbrush is like any tool. It's what you get comfortable with. A lot of people over time end up with 2 or more airbrushes depending on what they're using them for, what they find comfortable to use etc. Some like the front trigger styles while others like the top control. People do great work with a Paasche H which is a simple single action suction airbrush. Others prefer the more complicated but more versatile gravity feed double action brushes. Suction feeds need slightly more air pressure to draw up the paint. If you're just starting a Paasche H would be a great place to start and guys like Donn Yost & Doctor Cranky still use them in their work.
