I just looked at building a "premium" dynamo wheel as a project - Alfine or LX dynamo, and A23 and CX-ray spokes - and it was too expensive, $300 for the parts. But Taylor in Germany will sell you a decent-enough dynamo wheel for quite cheap, mostly with Shimano 3N31 hubs. Some of them are listed <$40 sans tax and before shipping. I found a matched front dynamo / rear 8-speed set that was about $200 shipped. Tempting!
