I'm going to throw my 2 cents in here. I would recommend the Nikon Coolpix line. I only use Nikon, and my family only uses Nikon now, and I've recommended them to all of my friends. We have 6 Coolpix's and one Nikon SLR in my house currently, and never had a problem. My first camera, the Coolpix 2100, was dropped off of a table twice (the cat seems to think it's a soccer ball), taken to the beach, gotten wet in the snow, thrown in my purse, etc, and still works fine. It's easy to use, and they now come with the built in "help" feature, that is basically the manual built directly into the camera. Some of the new coolpix's have the "manual" option as well. They all take two double A's, and most if not all take the SD cards. Plus, you have the Nikkor lens, which they are famous for, that takes amazingly crisp pictures. And, you said your daughter loves macro settings, and the Nikons have some of the best capabilites as far as macro goes, that I've ever seen.
(And no, I'm not a representative for Nikon, I just love them so much!)
