The KCNC work pretty good, though I'm relatively lightweight. Retail looks to be about $70, and I think they have a pretty good rep, so they don't usually get discounted a lot.

If you do ebay, there are different lightweight skewers that you can get for less. But some of them use plastic at the cam which may or may not be durable. The KCNC "socket" is round and metal, so less sensitive to positioning and possibly more durable. They got a good review in a skewer roundup at Roues Artisanal: http://www.rouesartisanales.com/article-28730729.html

Edited to add: I currently use KCNC, Aerozine, and Zipp Ti (the older ones, not the newer aero ones) skewers on my road bikes. KCNC are my favorite for the balance between ease of use, lever feel, weight, and looks.
