Canon Powershot SX10 Digital Camera

My nephew wants to buy himself a Canon Powershot SX10 Camera with his savings and birthday money. He likes to visit airshows and this camera has 20x zoom and optical image stabiliser which should be pretty good for the job.

Pixmania have it for £278 inc vat + Delivery but can anyone beat this significantly?

BTW - the SX20 has been released, or is very close to release, so this should mean that there should be a few deals to be had on this one.

All help gratefully received.
