Been surfing for the best 1080 with 100hz TV - 40" or over. Stumbled across PC World and the SAMSUNG LE40A656 (same specs - slightly different shape) for £699
I noticed the 686 online at Comet and wanted to nip in for a look. It was in store for £799. Mentioned this to the sales person who gladly knocked the price down after checking my querie. After all i only needed to go home and do some clicking.
The 656 is at Richer sounds for £649 if you have one close:
