Dynohubs are a little expensive. I would go with either the SON or the Shimano 3N72. The Shimano hub is about $110.00, the SON about $260.00. I have both, they both perform the same as far as drag and electrical output. The SON is built better, has cartridge bearings that are not user serviceable, hub has to go back to an authorized dealer when the bearings need serviced. The Shimano has loosed cup and cone bearings, difficult to service but not impossible.

Headlights on the other hand are very expensive. They have alot of very expensive, complicated electronics. I have been using some home built LED headlights all winter. I have found that for a fraction of the cost and a little work I can put more light on the street with my home made lights than with my 2009 model Supernova E3.

A bunch of good info here on DIY lights:
