I just put together new wheels for my 2007 Allez double, and had the same stock wheels as you. I agree that the stuck hubs are horrible, as noted in another thread, I have a wobbly cassette, and the axle bearings are crunchy. The new wheels are built with Kinlin XR-270 rims, which look almost identical to the Specialized rims. If you are up for a challenge, you could rebuild the wheels with new spokes and hubs.
