(From the OP): Just a reminder that I DO already own a light. It's a 10w Niterider from around 1997 that cost about $169 back then. At this point, it's a great "see" light for about seven minutes. After that, it's a sufficient "be seen" light. I was hoping to find something at least as bright as this was 15 years ago, and preferably something that runs on AA or AAA batteries, as I don't like having to worry about keeping the charge up during the deep winter months when I'm not using it.

Still...PLEASE...no more recommendations! I'm convinced that, as soon as my current light drops completely dead, the thing to do is walk into the LBS and buy whatever I can afford with the change in my pocket. Then, after six months or a year, I'll throw it away and become part of the problem with the world.
