Look at the Weinmann dp18. Get it in a 36 spoke configuration. It's not quite the quality of the Velocity wheels, but it'll work. Make sure they are at least hand tensioned, and preferabley hand built and tensioned with a 14 gage spoke. I've had great luck with straight gage spokes on my wheels, but viewpoints differ on butted, double butted, or triple butted spokes.
