Your right, I would much rather spend several hundred dollars for a indoor booth that vents the over-spray and toxic fumes out of the window,how ever filtered and the drier being adjustable for different drying speeds.that is something a wood framed structure with card board sides could not support,I was just commenting on how in the garage you could build a portable booth with little money,my focus was on the booth not the blower,or drier,which could be added to a wood framed structure just as easily as a metal structure,I'm sure Jeff is capable of making his choice,I simple offered another building material nothing more.Good luck on your booth,hope it works out for you.Blake http://www.eng-tips.com/viewthread.cfm?qid=161726
