Agreed that there are some crazy prices for lights out there. One problem with buying lights is that there is no really good way to do a cost benefit analysis. With parts, I have no problems in doing a cost benefit analysis. With lights, the costs are so tremendous that it's easy to justify overspending on lights. So I paid more than $40 for my headlight and I'm really happy with it. It's a light and motion commuter 550 which I picked up on a blowout for under $100. It probably costs even less now.
