Where to buy Arduino board and kit in London?

Hi...

I need to buy an Arduino board and a good components kit in London. I'm a noob and I need something to get started with. Does anyone know any shops in Central or Northern London if possible?

Cheers,
Tarun

I used yerobot on ebay he is in England somewhere. The only thing is shipment is really slow.

Thank you. I've finally ordered my kit from SKPANG. A 328 Board and helluva lot of components. I just don't like the price very much.
