The high-end shimano dynohubs (DH-3N70 and 3N71) are nearly as good as the schmidt's for less than half the cost. The low end (NX-30) are crap, so avoid those. But don't lump the nice stuff in with the crap.

You can also get pre-built (3N70 laced to salsa delgado) wheels for around ~$115 from QBP, which should put a nice lighting system under $200.
