As a substitute, I'd go for the Mavic Open Pro with Ultegra hubs. Performancebike.com has the wheel set for $199.
If you have a Performance shop in your area, you might want to check for those wheels there. I went to one nearby with plans to buy those wheels at $199.99. They had them on sale at the shop for $168.98. They've been fine for me, but I only weigh 190lbs.
