I can't reccommend enough that you look into hand builts wheels. Look at this page..
http://www.bicyclewheelwarehouse.com/ see what they would charge to build the kind of wheels you want. I have one set of Open pros with Dura Ace hubs that have been working for years. If they can build them in the price range you need chances are a wheel builder close to you will as well. I would also reccommend round spokes because every bike shop carries them. No big deal when wheels are new but sooner or later you may break a PITA. And if you do decide to order from these people they will come ready to ride.
