My first spray booth was a plastic tub with 2 muffin fans. It did OK, but a little too small, and I wanted a little better air flow.
Got the idea to built a box from here:

Being the cheapskate that I am, I did not want to spend the $230 (including shipping), and had read about using a marine blower for a fan, so thought I would give that a try. So this is what I used.

I used OSB rather than plywood, as I am a horrible carpenter, and figured it would take me a couple of tries to get things to fit. Plywood would definitely look a lot better.
If I were to do it again, I would probably not go as wide, and shorten it an inch. Using the plans, but not ordering the parts that included the filter bracket/holder, I was an inch too tall to just slip in a 24X16 inch filter, so had to mess around to find a way to hold the filter securely in place.
The booth works extremely well, and I am mostly happy with it, but that blower is loud! Can hardly hear the airbrush over the noise, but it does provide excellent air flow.
