DX Zoom-Nikkor Lens? I am investing in a camera after using my Dads for the past year. I was going to try out the 18-200mm lens and then accumulate lenses in the future when I work for more money. So I need help to look for this specific package which would include a Nikon D-80, and a 18-200mm lens. If you have any other suggestions please tell me... TY
