Dedicated wheels for racing and training
 

I've got a stock '06 Kona JTS. I plan to use the stock wheel as around town wheels with a Burley trailer hitch skewer in the rear wheel. I can also put a normal skewer in the wheel on race day and use the wheels as a spare set in case of emergency.

I've read a lot of positive opinions on the Open Pro/Ultegra combo as a good set of wheels for racing. Are there any other relatively cheap options that I should look at? I don't plan to use tubular tires anytime soon, so I'm looking for clincher rims. Thanks everyone.
