Vacuum systems

[Ken Landaiche <ken_landaiche@dlcc.com>]

I was just in the local Home Depot and noticed a dust collection system
being sold by Ridgid. I thought it was pretty slick, with the clear
tubes and gated connections for dust hoses. A portable Ridgid shop vac
provided the suction. 

But then I got to thinking that commercial shops must use something both
more robust and more flexible, at least in the fittings offered. What
experience do you listers have in permanent vacuum and dust collection
systems?
