Im looking into purchasing my wife a nice camera for Christmas. Right now she has a Kodak z1012is, and I was looking into getting her a dslr camera. The model of cameras I was looking at are the Nikon D5000 with 18-55mm lens, or the Canon Rebel xsi with 18-55mm lens. Which camera would be a better for her. She has never used dslr cameras so this would be her first. Thanks in advance.
