i got a record power DX 1000 which is fine for suction but as noisy as ****, 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
