I bought a set of 650b wheels, Weinmann zac rims, Deore hubs, DT spokes, from an ebay seller about 6 months ago for $90. Can't find the guy now, though, as it seems that ebay is only keeping 60 days of buying history. I ended up relacing them because some of the nipples were rounded, but still, decent wheels at a good price. I wish I could find another pair for the bike I'm building for my wife. He had a similar deal for 700c wheels.
