I think this is a great deal for a Full HD Sony Smart TV with added 3D. I have the 32" model and everything about it bar the 3D is fantastic.
Note: Amazon also have a 'like new' version of this TV for £449.99 which is an absolute bargain for this great TV. Product will very likely be new - I've bought 2 monitors and a speaker package in 'like new' condition from Amazon and products were brand new. It'll be one lucky punter who buys this at less than 450 smackers.
