Anyone use an airbrush? Looking to buy.

I'm looking to buy an airbrush sometime after I get my credit card paid off, and I'm trying to get some info. Not planning on doing a whole lot of fine-detail work. I'll be using it for modelling, mostly for primer/basecoat and some larger details. Basically, I want a workhorse brush that will handle large volumes and thicker paint, but still let me do some moderate detail as well. If I decide I want to do fine-detail airbrushing, I'll buy a second brush.

I'm currently looking at the Iwata Eclipse HP-BCS, in a kit with a 1/8 watt 60psi oilless compressor and a couple of odds and sods for about $250 plus shipping. I'd like to find something a bit less expensive, but I doubt I'll be able to if I want a decent compressor.

I've also seen a lot of Airbrush City stuff on eBay, but I've read mixed reviews about their brushes.
