Been looking all over for one of these before Pioneer stop production in 2010
John Lewis retail these at £3,995 (inc 5 year warranty and stand)
Currys £3,799.99 (1 year warranty and stand)
Richer Sounds £3149.95(1 year warranty, no stand)
You don't get a stand for £3195 price but you can pick one up for around £100
To get the 5 year warranty you have to buy from the shop in Bolton.
I understand that this isn't exactly cheap for a TV but it is the very best money can buy and you save around £800 on the list price. You also get the 5 year warranty which is worth anywhere in the region of £300 to £500.
Also due to the high demand for this TV expect to wait up to a month for them to get stock.
