Planet Bike has a pair, the Taurus, and they are relatively inexpensive at $18 MSRP. I got a pair last summer. They don't really last for more than a season, but at that price I'm not worrying about longevity. And since it's Planet Bike, it means you can find them in a lot of places.

Rivendell has their "Summer Gloves" at $15, fairly similar to the Planet Bike ones.
