Buy a Digi Camera at airport?

[pmw5]

Hi,

I am going from London to Oz via Singapore. Unfortunately we don't stop overnight in Singapore until the journey home which is a bit of a pain as I want to buy a camera to take photos in Oz.

However, we do transit in Singapore on the way out, and will have about 1 hours in the airport where we can shop.

Are there camera shops in the airport? If so, would anyone have any idea how much I could expect to pay for either:

Nikon Coolpix 8800
Canon EOS 20D.

Many thanks in advance for your help!

Pete
