You might look for some older Deore LX or Deore XT hubs. There are a lot of these floating around on ebay. I bought a nice set of nos Deore Lx black anodized hubs with both Uniglide or Hyperglide threads on the cassette body - for under $25. Then I bought a 137mm replacement axle for it from Wheels Manufacturing. These replacement axles are very high quality and cost less than 15$. I haven't built the wheels up yet but am looking forward to doing this soon. The bearing dust cap design looks like it spins along with the axle which could add some friction. The Deore XT and XTR hubs can be adapted for the road and the early ones I've seen seem to share a similar dust cap to Dura Ace. These cost a fair amount more though, even used.
