You get what you pay for.

I recently bought a Nikon 7600. One can't expect a camera in this price range to be perfect. The first one I bought had to be changed for a new one because it had a few faulty pixels in the CCD (they always appeared blue). They were extemely visible in dark photos. And the second one has one faulty pixel, always red. I'll put up with this one given that it's hardly visible unless you go looking for it zooming up the photo. I agree that the camera has poor quality in dark areas but you must admit that the specifications say that the camera's sensibility is equivelent to ISO 200 at best. Before this camera I had a 3Mp Sony that had a ISO 400 equivelent sensibility and took better pictures in the same poor lighting conditions. So if one knows a little bit about "old fashioned" photography one would know what to expect from the nikon 7600 specifications sheet.
The 7600 cost me 199 euros, in November 2005. For that price I'm quite happy with this camera, in spite of all it's defects.
