Dude, head to Slowtwitch Classifieds section. There are tons of wheels on there this time of year, some pretty good. I just sold the Shimano RS550s WITH the Ultegra 12-25 Cassette (pulled from a new P2C and I never rode them) for $150 shipped to the East Coast (not that they are great wheels, but just an indication of some of the deals). And there's a huge amount of HED 3s on there right now.
