Happy to help! :) I have the lightbox that I linked to -- the LightTracer II -- and it's still going strong after six years. They're really durable.

Edit: If your daughter's interested in drawing things directly in Gimp, rather than scanning them in -- the final image quality is so much higher if you draw them digitally -- you might try getting her the entry-level Wacom tablet, the Bamboo Pen. It's on sale at Amazon for $50 right now, which is an unbeatable deal. :)
