Where to find a replacement charger in Paris, France

Hi All,

I'm travelling at the moment and am having problems with my iBook G4 adapter.

There appears to be some kind of faulty connection within the charger itself. Sometimes when I plug it into the computer, no light whatsoever appears. If I jiggle the square charger part, the light turns on.

The green light is on now but I'm afraid to move the adapter / computer in case this loose connection fails completely.

I would simply unplug the computer and put it away until I get home except I rely on it for, well... everything!

I'm in Paris, France and am wondering if someone could recommend a place where I might be able to find a replacement adapter, preferably a used or third-party product.

My iBook is nearly 5 years old so I don't want to spend too much on a new part as I plan to buy a new machine (MacBook Pro) upon my return to Canada in August.

Any tips would be much appreciated.

Merci!
