Looking for a cheapish wheelset for a cross/road bike.

Need: Shimano freehub, 700c, clincher, 10-speed compatible

Would love to spend under $300, but might pay up to $500 for a really nice set (ie: Mavic open pros on King hubs).

Looking at things like:
Mavic Ksyrium Equipe/Elite (prefer silver)
Easton EA70
Shimano Ultegra/Dura Ace
Customs

Will of course consider other similar wheels (fulcrum, etc)

If you have anything you'd consider parting with please email me at 2.99792e8(at)gmail(.com). Would be a great way to get rid of a stock wheelset you upgraded...
