That's a pretty cute little system that Seyco has. Kinda pricey though. I just recently built a system for my Dewalt. I have the saw at one end of my little shop and a Fein vacuum at the other end. It sits atop a stand and is plumbed into a Dust Deputy that sits below it. I use the Fein for my shop vac to clean up everything from floor to ceiling because it has a 16 foot hose. I built the pvc system for the saw and managed to plumb it in such a way that the Fein hose just plugs into it when I want to use it. As Scrappile said, the suction noise of the pvc pipe is more than the vac noise. It comes on with the saw and turns off when the saw shuts down. It works great. I found the Fein on C/L for a great price and I think that I have about $20 invested in the pvc piping and hook up. Of course, I over spent on the DD and should have just bought the barebones unit for about $50. I now have an extra bucket, wheels and hardware. I did use the hose and 90 degree adaptor that came with it but they could have been purchased separately. Anyway, all told, I have $295 invested but that could have been $50 less. I realize that the $175 for the Fein was my lucky day. It is quiet though so well worth the investment even if you have to go with a new unit. I have shown these pics before but since this is a new thread, I'll attach them again.
