Pop Gadget has been publishing some nice Christmas Gift Guides for this year, and divided them into categories like price and "age". There are actually 5 Guides but I guess more will be added soon.

From the Gift Guides for the Kids there are some cool ones. I would recommend: the "Hole-On Ex Paper Camera Kit - a great learning project and introduction to photography", this camera is made of paper; and the frog Speakers. Read more Gifts for the Kids at Pop Gadget and get to know where to buy them.

There is another category about gifts between $100 to $400 and you can see them all here. The ones I like the most are the Garmin GPS, and the SleepTracker
