Wheel Dynamo LED Light/Phone Charger--What's it Worth?

http://i51.tinypic.com/2v0mobd.jpg

I saw this at Interbike. It's a 1W LED light with a rechargeable
standlight battery, and the ability to charge a phone or iPod.

How much do you think such an item could be sold for? I think the
manufacturer is asking way too much, and that it might sell for $35
retail, but the pricing is such that it would have to be $75 by the time
it got to a retail store.
