Query: These cameras are defective within 1-2 years

I had the Nikon Coolpix S3 for about 14 months (of course the warranty ended after 12), and the screen went black all of a sudden. You can still view old pictures, but all new pictures come out completely black. This is apparently a VERY common problem with Nikons, particularly this model. They have a service advisory for several other Coolpix models to fix this same problem, but not for the S3-S6 models - and Nikon will charge you a significant amount of money to fix it. DO NOT get suckered into buying this camera, or any Nikon for that matter - I was extrememly disappointed with the camera, but especially with their service.
