Just spotted a link from HDTV Test site for offer of VAT back from Sony on the 40EX503 TV. The link goes to AMAZON where offer is confirmed. Not sure if this applies to all Sony models.
Cracking reviews of this TV everywhere.

I know when it comes to taxation it might not be as simple as taking off 17.5% off the list price to achieve a price without VAT. May be some accountant or mathmatician can figure out the methodolgy for doing this.
By my reckoning the price comes to £457.10 but I have referred to the price posted by HDTV Test on their site for this posting.
Offer until midnight 24th Dec 2010
