PM me - I have 2 wheelsets lying around that I don't use anymore - one a Shimano 550, one a Neuvation M28. In both cases I had trouble with the rear wheel, but the front is fine. Not the greatest commuter wheels (both are low spoke count, the Neuvation is fairly stiff), but the Neuvation in particular has a reputation for being strong.
FWIW, I was able to flex the rear 550 into the brake pads on climbs, and after about 10k miles I started breaking spokes on the rear Neuvation, which is why I moved on to different wheels.
edit: if you want an idea of what the Neuvations are like, the Forte Titans sold by Performance are almost identical - the hubs and rims look like they are the same, the Neuvations have slightly wider spokes.
