Cheap, but Cool Gadgets

I enjoy having gadgets around to mess around with, but at the same time I'm cheap and will be hesitant to purchase them. I found this website yesterday of 10 cheap gadgets for under $10. Many of them are from ThinkGeek which I check from time to time just to see what they have. I had seen the Annoy-a-tron before and think it's something that would be great as a prank.
