I priced out a dynamo system and got scared off by the cost. Thinking out loud in not particularly C+V tone , I might pick up a MagicShine set up. That way I can move it to a different bike if I'm planning on being out all night. To keep in the spirit of C+V I can make a rack mount for a silver b cell mag light and add a retro-esque tail light for local outings. Maybe after I actual do a couple centuries, I'll be able to justify the expense. The Sanyo, I will save for a more of a period piece project.
