I had Universalcycles.com build my wheelset. They did a good job for a fair price. I got Hope Pro II hubs with DT EX5.1d rims and DT Comp spokes with brass nipples. A shade under 5 bills. Saved me $250 over my LBS. I got a good 100mi or so re-tension (as one should for pretty-much all new wheels AFAIK) and they've been excellent. I did accidentally smack a rock with the rear and had to quickie-hit it with a spoke wrench, but when I built my RM Flow, I took it downtown and jumped off some stairs...slant wall ride-hop-to-flat, and some other urban stuff. Still straight as an arrow.

They do good work.

Bicyclewheelwarehouse.com is a pretty popular choice for good deals on wheels.
