Have you noticed the price of cameras dropping? How do you think they can cut the prices? They make the cameras cheaper. By upgrading to that new camera, you may be actually buying a camera that is not as well built as the one you currently own. So, if you have a camera that you know how to operate and don't want to have to learn a new camera, then you may want to consider
repairing it rather than replacing it. By repairing your camera, you are keeping one more camera from going to the landfill.
