Other wise Wheelsmith seem vague about buying just rims.
I read on their site that they had stopped selling parts and now sell complete wheels only.
These guys in Germany have them really cheap. Labelled CNC rims, but I'm pretty sure they're Niobidium jobbies. there will be an extra delivery cost for bulky items, and you'll have to pay by bank transfer. But they seem a decent shop to deal with. http://www.cnc-bike.de/
