My work area is temporarily in my basement. I'll say this.....even if only running 1 machine at a time, if you are concerned about dust, go as far as your budget and space will allow with regard to dust collection. I don't feel its worth the health risks or mess to look at it any other way. It would be hard to go overkill with your dust collection. I'm running a 2 hp JET cyclone dust collector and air filter. My basement is NOT large!
