I was going to purchase it and decided against it. It's probably still good for airbrushing but I'm not airbrushing for hours so it's not worth it. I built a little funnel-like cardboard box to spray my minis in that I use in my backyard (I just sit it on top of my garbage can). It basically directs most of the primer into one direction. It was simple and only cost me a medium sized cardboard moving box from home depot. It helps keep the spray from going all over the place on windy days.
I can't imagine the Airbrush spray booth being useful from primer cans.
