If you're a Nikon camera user..customer service is more reliable than Canon.Lucky for you.Now Canon pursues their profit and they don't hesitate to annouce a recallment 3 years later after malfunction was claimed by many people.(I use Canon products.That's why I can say.)

If your camera is completely dead away from your home, here it is.
Go to see the second hand camera shops.Good amounts at a reasonable price.

For example,I recommend Map Camera in Shinjyuku and Fujiya Camera in Nakano(10 minutes by train from Shinjyuku).Lots of Second Hand Cameras are available,compared with these kind of shops in your city and town.
