I've got a $100, what light should I get?

[gigantic]

I've gotta wonder though, can they take a beating?

so far so good with mine. I'm super extra tall and have bumped branches hard with it, it keeps on going. The construction is super solid. The chassis appears to be machined out of billet aluminum. do a search on amazon and get yourself a "magic shine wide angle lens" and put that one on your handlebar light. That way, you get a broad spread of light, and a sharp, focussed beam where you point your head.
