Don't have an airbrush yet? I just bought my first one a few months ago. Tamiya Spray Work...I already completed one 1/35 M1 tank (and currently working on another), and it really seems to be okay.
I can recommend it, although since it was first - and only -airbrush (after 20-odd years of handbrushing) I really can't provide a comparison with other airbrushes.
Maintenance and cleaning is very easy and quick (since I use only Acrylics), te only thing I dislike about it is it is tricky to adjust the amount of paint since its a single action (or a hybrid) type.
The compressor can get deafening but its primarily due to how I arrange my gear (the thing is less than 2 feet away from my right ear).
Spent a little over P5,000 Php for it as well as a power supply; bought it at Lil's.
You may want to consider that as a starter; then eventually move on and upgrade to their HG-types, (prices are similar to airbrushes you saw in National...Badger, whatever). At least it's compatible with the compressor.

BTW, I then assume you hand-painted that B-17...quite impressive, I must say.
