I know, not a fit you'd probably think of, but the folks at Edge have kindly set me up with an account. If you've got the scratch, they're supposed to be some of the trickest wheels (and other carbon goods) out there.
Some sample pricing (remember, this is frame customers only, I'm not a retail shop):
Edge All Mountain or XC 29" rims/DT 240 hubs $1850
AM or XC rims/King hubs $1950
Cyclocross fork $375
1.0 Road fork $435
