Managed to pick up a Sony KD-49XG9005 at the weekend as an open box item with full 6 year warranty for £800.
Very impressed so far and quite an upgrade over the LG 43UJ630V it replaced. Always worth a look in a local Richer Sounds you never know what you might find.
Got mine on Friday for £799 from RS - turning up tomorrow hopefully. Shame I don't have room for the 55" version (think it was buttons more) but can't change my room size!
