Good thinking WCD! I'd forgotten about those even though I have their site bookmarked.
On the Eastwood ones, I got the one with a long wand/nozzle that you fill and pressurize with the air compressor; disappointing in my experience, didn't atomize well and seemed like it needed more pressurizing that you can do (I was using it with a big commerical compressor). Somebody else might have better luck though, never know...
