Let me start by saying that I understand this is a relatively expensive booth and not what everyone is looking for. That's totally understandable.
I started researching small hobby booths a few months ago. It looks like quite a few are the same product rebranded by several companies. Many of them also say that they are not intended for use with solvent based paints. IMO, that kind of defeats the purpose.
My search for "explosion proof" booths or exhaust fans led me to this website:

After exchanging a few emails with the owner, I placed an order for the 36" model. It arrived this week and I set it up today.
My first impression came from the box itself. It was very solid and well marked to (hopefully) prevent rough handling. Inside, the booth was packed in thick styrofoam and all the edges were reinforced with sheet metal angles screwed together at the corners. The booth was perfectly protected inside.
Assembly effort was minimal. It consisted of fastening the extended work surface to the front with the provided brackets and screws. Everything lined up without difficulty.
I set it up with a 4" flexible metal duct exhausted through an exterior wall. The airflow pulls the vapor and overspray away quickly enough that you don't even see it. Filter is a standard 12x20x1 furnace filter. The interior lighting with two 60w LED bulbs is more than adequate.
Yes, this was an expensive hobby purchase, but I'm confident that the satisfaction of having a quality AMERICAN MADE booth sitting on my bench will last long after the price is forgotten.
