Black Images Problem Reported

NikonNoob

I am wanting to purchase the D5100. I was pretty excited until I read some reviews on Amazon and Nikon Rumors Forum. The problem reported had to do with the camera, after using it for a bit (less than 60 days), starts producing black images. In one report, a person had to send his camera for repairs (shutter mechanism & blades replaced).
My question is, do you have any opinion on this matter? Should I be worried about it? I just love the camera but I'm a little hesitant.
In all fairness, I do belong to another forum where a lot of folks love the camera and have had no problems.
