I really wanted the climate control so I did what it took to be able to work inside the house.
I use a down draft table and a dust collector when I use the power sander, yes it is loud, but with the door closed my wife does not think it is to loud out in the rest of the house. I only use the big machine when I use the belt sander or the palm sander.
I also have a dust collector fan I made out of a surplused equipment rack fan, it is not very noisy and does a pretty good job.
These machines will work really good for fine airborn dust collection http://www.sears.com/shc/s/p_10153_1...dust+collector http://www.sears.com/shc/s/p_10153_1...dust+collector
