i got a record power DX 1000 which is fine for suction but as noisy as hell, so am thinking of replacing it as driving me mad, im looking at the Cam Vac 286-3, and have found a link in this site where they connect a exhaust pipe to a sound box and quietens it down no end , i only use mine for sanding on a lathe, and watched a demo wher he was using a cam vac with sanding hood and it was quite impressive
