Ok, so I have questions on this, too. I was looking at the Cygolite Hi-Flux 200, the Niterider Sol (a little more expensive) or a $40 shipped Niterirder Digital Night-Owl II. I'm tempted to do the cheaper route because it's lots of money I can save, but I have a 30 mile RT commute, and at least half of it will be in the dark soon. What is my best option?
