I'm currently using a couple of 5W NiMh Cateye lights which provide enough light for the off road commute but as I already have a Son dynamo hub I'm thinking of making use of that. So is anyone else using a dynamo driven light and what model. I'm aware of the supernova triple which looks good but ridiculously expensive for just a light. Is there anything else out there to consider? It's only for easy cross country terrain and as I'm riding alone and a coward I tend to be cautious anyway.

Not tried one myself but the dynamo subject has a good following on Candlepowerforums bicycle section.
