A couple of weeks ago I picked up a Grizzly 440 2hp cyclone unit with the 25% MS CB deal. I got it setup over the course of a couple of nights on a shopmade wooden stand but then took another little while to revamp the shop, build a sound absorbing closet around the thing and get the ductwork installed. Can't say I'm finished with the ductwork yet but I do have my Unisaw w/overhead guard and jointer connected and got to suck up some dust for the firt time. Very happy with the performance so far and very happy with how much the closet cut down the noise. Before the closet that sucker was LOUD . Now it's quiet enough to leave on for lengthy periods and not too noticable in the kitchen above the shop either. The Closet is 2*4 studs + fibreglass insulation, I built the door out of a 2*4 frame with a skinning of 1/4" ply on one side and pegboard rough side in on the inside. The top of the closet is just a 4*6 foot sheet of pegboard laid on top rough side in with a layer of the glass insulation added on top.
