It does seem to be too good to be true, doesn't it? But it's not!
Bear Air is highly regarded as an online airbrush source, and as a Badger 150 owner I think you have to look far and wide to find a better dual action siphon feed AB!
If you want too good to be believed, I'm looking at buying a clone of the Badger 100LG for only $39.99 (about $35 US). I'm assured that if I don't like it I can get my money back.
