New Rear Wheel suggestions

I've been running a set of Ritchey OCR Disc wheels on my Santa Cruz Blur used for XC. I need to replace my rear wheel do to driving over it with a car (don't ask..). Should I drop the money for a complete new set of wheels, or just a good rear wheel? I absolutely love the sound of the Chris King hubs, and could get a rear built with one but certainly cant afford a set.

Any suggestions???
