Hello, I am currently looking for a camera for my wife. I am seriously considering the Casio EX-Z40 for my wife due to the small size, decent optical zoom, and large LCD. However, one of the things I need to be able to do is charge batteries when traveling to Europe (and other places). Is there some sort of universal travel charger available for this camera/battery? The other option is disposable batteries like the AA's used by the Sony DSC-W1, but I don't believe there is a disposable option for the casio.
