You're welcome!

I recently went through your same exercise to find a good tail light. I wanted the DiNotte tail light (approx $150 US). I bought the Planet Bike Super Flash (less than $20 on sale). Someday (perhaps), the DiNotte. For now, the Super Flash.

I also have the Cateye TL-LD1000 (another nice tail light, probably not quite as effective as the Super Flash in a few ways and more more expensive than the Super Flash). But you will have read about the Cateye in the review on CandlePower Forums that I linked.
