Under the Tips, Tricks and Tutorials category, there is a 15 page thread on paint booths. It's locked so it is at the top of the screen. There are a lot of tips and good advice there. If you want something inexpensive, you may want to consider making one yourself. I bought a small unit from a company that advertises in the modelling magazines. The name escapes me as I am away from home, but it was between $300 and $400. I like the unit and do not have any complaints, but if I had to do it all over again, I think I would build my own.
