IMHO, Nikon SHOULD be interested in your story. If they are "too big to care," they will soon be "too small to do business with."
People like us who buy their products, are buying primarily on their past reputation. If they develop a bad reputation, or allow their authorized repair stations to rip people off, they won't have us as customers very much longer. We'll just shift all our stuff to another manufacturer and be on our way. We photographers are funny that way, huh? haha
