Found this while looking for a cheap first digital camera for the kids.
Not sure that it is entirely suitable for that purpose as it is very small, but for under £15 delivered thought it was a good deal. Ad says that previously it was nearly £100 which doesn't sound quite right and it says that the deal expires on the 20th.
Can't find any reviews on it but what attracted me was the colour screen. It is a low resolution camera so wouldn't expect the images to be very good and it doesn't have a flash.
This tiny and unique mini camera is small enough to take with you everywhere
With the 300,000 CMOS sensor you can take excellent images and view them on the exclusive 1.1 inch colour screen first
Accessories include CR2 battery, CD driver and USB cable
Its the tiny size of 6cm x 4cm and comes with a keyring attachment
