I bought the smaller Delta (maybe 1 HP?) many years ago, recently upgraded with the Wynn filter and a home-made separator (using Rockler fittings) - don't think that HF was around 30 years ago, but bought the DC as part of the saw, fence, mobile base and DC package from a local supply house. It sits kind of in the middle of the shop and I move the hose from machine to machine as needed - I have the old Rockler QD fittings on the TS and router table, sure wish they still made them as the new ones don't fit nearly as well. Only need a short hose when it's hooked up to the saw, have a longer hose when I need to stretch over to the router table or miter saw - I get aggravated with the sloppy fit on the new Rockler fittings, and have considered taking them off and just using a hose clamp.
I have a "vintage" shop vac with Rockler separator that I use for the smaller machines and hand-held tools - it's old and tired and I've replaced it with a Festool/Dust deputy which I haven't managed to get out of the box yet.
