My dynamo setup cost me $275, including shipping. It consists of a Shimano 3N72 hub, spokes, nipples, an XM317 rim brake rim, tape, the spoke wrench, and a B&M Cyo Premium light. It puts out an incredible amount of light. I also didn't go with a dynamo taillight, but I have a MagnicLight on order for that, if he ever actually ships them. I built the wheel myself, and then bought a tensionometer and rebuilt it when I found it wasn't nearly as tight as I thought. It is pretty satisfying to build your own wheels. I also built a back wheel to match but that isn't included in the stated cost.
I would call this setup mid-range, between the Schmidt/Edelux and a bottle dynamo/discount light combos. You can't go wrong with this setup.
