If you have £400 burning a hole in your pocket why not nip down to your local Jessops or Dixons where you will find a Canon 400D with a kit lens for less than your budget.

You'll get a good camera with a warranty, and the security of buying from a recognised high street shop.

Dixons / Currys = £389.99
Jessops = £399.99

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
