I wouldn't hesitate to purchase used or refurbished from B&H, Adorama, or KEH. Generally, each gives you a chance to examine the camera in your hands and if it doesn't meet your expectations (within a reasonable time, usually a couple of days) you can return it. Of course, you are responsible for return shipping. Nikon USA also sells refurbished equipment.
I just purchased a refurbished Nikon zoom lens from B&H. It came with a 90 day warranty.
