I would look into wheels from Mike Garcia at
http://www.oddsandendos.com/ . Just search this forum and
www.mtbr.com for recommendations regarding his work. I just got a set of WTB LaserDisc Lite hubs w/ Velocity VXC rims and Supercomp spokes. He's friendly, will talk your ear off about wheels, and has great service. I think the care and quality that goes into his wheels make it a really good value. The above was $334 including shipping. I've heard lots of good things about Larry at
http://www.mtnhighcyclery.com/ also.
