Today only until 10:30 PM EDT, Karbon Speed wheels are just $999 rather than $1400 for the set. (Yes, that's for two wheels, not just one.) While they don't have the brand recognition of Zipps, they have been getting great reviews and there's a money back guarantee. Go to http://www.karbonspeed.com for more information.
Another option that you might want to look at is Flo. Same type of combo, but for $100 less. For the same type of combo, but with a disc rear will cost you about $1050. The only negative is they are on back order, but the season is almost over anyway :). For that price point, it's hard to go wrong with either companies for brand new wheels.
Be on the look out for KarbonSpeed coming on board as a club partner. We have been in talks with them for a few weeks/months now and we think they could bring great value to the club.
