I use that Paasche booth also, and it works great for paint fume evacuation. I spray in a room in my basement and, outside of that room, nobody would know I was spraying lacquers. I route my vent tube out my little sliding basement window. I made a plywood window insert with the tube epoxied into it. When not in use, the insert/tube rest on the inside windowsill. When it's paint time, slide open the window, pop in the insert, and spray. I highly recommend you get one of these booths!
