I own a Paasche single action airbrush and this past Christmas, I bought a Iwata Neo dual action. Here's the kicker, I can't use the Passche airhose with Iwata airbrush. Instead of investing $30-$40 on a new airhose for my Iwata airbrush, I bought an adapter to use the Paasche airhose with the Iwata airbrush. Adapter cost me $6. Money well spent is all I have to say.
