The little Cateye headlight I've been using for my early morning rides is less than ideal. It definately falls in the "be seen" category. My plan is to replace it with a dynamo hub and light. I would like a Schmidt Son 28 dynamo hub but the $275 price tag is a bit much for me right now.
I started researching the Shimano DH-3N70 dynamo hub. Much of what I've read indicated that most people were perfectly happy with their Shimano dynamo hubs despite the added resistance compared to the Schmidt. Many people actually recommend the Shimano over the Schmidt for city riding which is pretty much all I'm doing right now.
Yesterday in the Surly LHT and CC Group, Andrew from Austraila, posted pictures of his new Surly Cross Check built up with a Shimano DH-3N80 dynamo hub powering an awsome little Supernova E3 headlight. Here's a link to his Flickr page for more photos. Good looking bike Andrew.
These hubs aren't available in the U.S. but apparently they narrow the performance gap between the previous Shimano hub and the Schmidt. I couldn't find any reviews posted in english but I did find Roseversand, an online bike shop in Germany that sells them for 67 Euros ($97) plus 30 Euros ($40.00) shipping to the U.S.. That's a savings of about $138 depending on changing exchange rates and if I read things properly on the German web site.
By the way, I also discovered that there's a whole subculture of people who enjoy building freakishly bright headlights and modifying flashlights. You can find them at Candle Power Forums.
