OE quality wheels. Where?
 

Buddy's rear wheel is toast, we're lookin for a cheap replacement. All I can find are high-dollar replacement wheels that cost 3x what the bike cost...

What are the basics he's looking for in a wheel? Do you know any specs about the wheel that come on the bike? If not, what year/model is his bike?

We just need a 26" XC wheel, 7-spd hub. 32h I suppose is fine. Disc only (6 bolt) would be preferred, but not essential. I THINK 20mm axle, but... not real sure?

Have you checked jensonusa.com, excelsports.com, biketiresdirect.com and the like for the cheapest wheels they offer?

Here's one from jenson matching your description.
