After searching for an airbrush spray booth on line, I decided to just build one that would be powerful enough, and large enough, but not break the bank. I researched online through site after site, and this is what I decided on:
The front of the booth with a 1/48th F-100D for scale.
Rear of booth with 3/4 inch spacer for mounting the blower.
The blower, Dayton 1TDR3, $105 from E-bay. Shown with scratchbuilt exhaust bracket and 4" vent starter $4 at hardware store.
Side view.
Shown with common sized filter. Still need to figure out a system to hold filter in, although the suction will do it when blower is on.
Shown with final coats of paint.
I also have a light to install Utilitech #0406107 under cabinet LED light strip, which will provide plenty of light.
Here is a site that has plans for this booth, although I made some size changes due to the fact I could not find the size of filter they call for.

I will add a photo of the booth with light installed once the paint is dry!
