I also don't see the average cyclist or commuter need a 200 lumen light. I got a Cygolite Luxeon light (150 lumens, maybe), that is more than enough for anything, save maybe off-roading in the dark. The main thing you need for commuting is "be seen" visibility. That includes the tail-light, reflectors, reflective clothing, etc.

Most of these flashlight costs you're quoting don't include the battery cost. Last I checked, 4 AA's + Charger is still around $20 or more. Add that cost to any flashlight if you don't have the batteries bought already.
