Are there any known problems with quality with this particular brand?

I've got a 4gal, oil-less, double hot dog (sorry, don't know the
technical terms) extreme duty, contractor grade, blah, blah, blah unit
that hasn't been used very much at all. But, the check valve seems to
be busted (based on symptoms and web site description - item #5 under
technical support). I'm in the middle of a job, deperately trying to
finish and the thing craps out (after very few hours of use). Gonna
take it in for service or return, but just wondering about reputation
(it broke so fast I suspect it's a defect; the other question is, have
they fixed the design so that it doesn't recur).

I got nearly 10 years out of my first CH (same description as yours - w/
black tanks) doing construction day-in, day-out. The only problem was the
trail of ballbearings it left behind on the last day I not have the new
improved iron-fortified model (yellow now) - it has a bum switch but works
like a champ.
