Jim had a solid sounding point in here somewhere:
_How much are you willing to spend to safe guard a moped that may be worth several hundred dollars?_
Well, not much. But, how much would you be willing to pay to locate the person who stole your moped after all of your other security precautions failed?
I don't want to say that information is priceless, but I think it's probably worth a good bit more than even a particularly-favored, used moped.
