Diagnose Camera Problem? Canon S90

[photobuff524]

I wanted to ask if anyone in the community could perhaps help diagnose my camera problem. I believe it has something to do with the lens because I only see the image problem in some pictures but not others. The image defect appears as a curved, darker section running vertically through the right half of the photo. Please advise if you have any theories or suggestions. Should I get this repaired or for the cost am I better off just getting a new camera?

Below is a link to a few pictures with the defect to illustrate.

Looks like you lense is 'reflecting' your cylinders. Try cleaning it. If this still occurs, you MAY need to get youself a new lens.
