That's a better price, didn't know that. I like the advanced features of the D7000, but that is more my style than hers. The D5200 may be a better balance between picture excellence and camera complexity for her.
I think I'll hold off and we'll try the D5200. If it doesn't feel right in her hands then the worst case is buying a nearly new D7000 from someone upgrading to the D4/800/e/600/7200/400/9000.
