I have a Nikon N2000 and a pentax ME super and was wondering If its still possible to to get the shutter replaced? I know its most likely cheaper to buy another body on ebay or something but I really want to keep these cameras like new since they are so old. What would be a typical cost of a shutter replacement? I found a replacement shutter for the nikon thats 40 dollars, but where can you find a pentax one and how much does installation cost?
