I have seen sets of mavic kysirium sl on eBay in that price range.
You have almost limitless options on pro wheel builder (non carbon) for that udget and on the bicycle wheel warehouse site I don't think they have a stock set over that price.
Heck at excel sports out of boulder you could even get a set of power tap wheels for just a little more....shoot I have seen zipp 101 for almost that cheap.
Bottom line is I don't think you need to get sucked into,the normal Clyde rim choices. If you are going to stay under 220 and want lit rims, there are plenty of durable choices.
