Thx for the info.
I tell you whut, I'm a cheapskate and I always try to buy generic, non-bike-brand when possible (thus my headlight being a regular flashlight and two hose clamps), but my wife found a Cygolite Hotshot on the road (fell off somebody else's bike), I bought a rack bracket and put it on my commuter, it is Amazeballs! I like it so much I would definitely pay the $35 or so to replace it if I lost it.
