If you can't afford the newer HED jet 6's or Zipp 404's with the wider braking surface (more aerodynamic), then the Sram S60's (older, but still exceptional semi-toriodal profile) are a great buy. The 80mm wheels are great, but if you race crits or like to do group rides in extremely windy normal OK conditions, they might be a bit much for some people. Make certain to pair a fast tire like one of the Vittoria cottons (Open Evo Corsa) with them.
Also, if you do some road racing, I think Mavic and Reynolds have great crash replacement warranties.
Overall tho, your fastest and cheapest setup is to run a set of wheels for racing and for training. I run an S80 front and disc cover rear with a set of the expensive Vittoria cottons, and then a set of cheap, durable Zaffiros or Gatorskins for my training wheels. Saves quite a bit of money on tires (not to mention wheels since I only had to buy one) with the kind of miles that I ride. But I'm also not nearly as fast in training as in racing.
