Summary: Bought a canon S90 at arond $770/- in end Nov 09 to bring along for a trip to NZ. After the 13 days trip, i notice the camera was not functioning properly and sent it to the service center. They said that it is badly corroded and wanted to charge me S$450 for the repiar. I was no where near the sea for my whole trip, how could corrossion occur. I suspect the product is already corroded before I purchase it.
