I had an old Wren single-action airbrush from Binks but it gave me fits. Now I'm using a Paasche VL double-action unit and it works like a dream. A while back Micro-mark had a pretty good deal on them.
I just went through the what airbrush to buy problem not so long ago. I settled on the Aztek A470. My friend had one of the less expencive Aztek models and I liked it very much. I got a good price on the A470 which is there best one and I am very happy with it. It even came with a VHS tape to show how to use it. I got mine at Micro-Mark.
