I found a pretty good deal on Craigslist the other day - an Iwata Eclipse airbrush & a bagful of spare parts for $25:
As I mentioned in my article on airbrushing, the Eclipse is a good choice for airbrushing models - this particular one is a side-feed brush, so it wouldn't seem to be ideal, but the Eclipse line is specifically designed to shoot thicker paints, so it's not a problem. The seller told me that his father was a graphic designer and had recently passed away - he was cleaning out the house, and put these on Craigslist.
The nice thing is that the airbrush came with spare 0.2mm needles & nozzles:
...the current Eclipse isn't available in 0.2mm, and can't be converted to my knowledge - you have to spend another hundred bucks on the Iwata High Performance Plus model to get 0.2mm. At some point the Eclipse series was redesigned (the new models have a cutaway handle) and Iwata must have changed this. If you look at the parts list for the High Performance Plus models, at the bottom there is a listing for the needle & nozzle for the "Original HP-B" - that's what this is. Pretty nice to get a 0.2mm Iwata airbrush for twenty-five bucks. The brush was pretty gummed up - I got the feeling it had been sitting for at least a decade, and I had to resort to pliers to get the old needle out. I gave the airbrush a thorough cleaning & put in one of the sets of still-in-the-package needle & nozzle, and it works great!
I also decided to greatly simplify my airbrush setup - previously I was running a manifold with a separate hose for each of my airbrushes, which required a ton of adapters & fittings, and was causing me to lose pressure. I went to a single-hose setup and added quick disconnects to all my airbrushes - here is a pic of everything that was removed from my setup:
...yeah, that's probably gonna make a difference...
