Luggage scale

I always thought some sort of gadget that you could hook to your luggage and pick it up to weigh what you have got in there would have been a good invention. Like all good inventions, someone else thought off it also. You can pick it from from ThinkGeek at: http://www.thinkgeek.com/gadgets/travelpower/aa38/

I'll file it away with my idea for the solar powered flashlight...
