I have one of the smaller Craftsman's, that's about 25yrs old and still going strong. Works so much better with a 2" dia hose.
My other shop vac is the small Fein, made in Italy. Very, very quiet, long OEM hose and powerful motor. Very expensive though. Found this one for a steal at a close-out sale.
I think my brother has one of the LARGE Craftsmans...it's a brute, VERY LOUD, clumsy, stiff hose, etc.
