Best value 46" to 50" TV (£450-550)

[RDC525]

I am looking for the best value 1080p TV available, ideally 46"+ and under £600.

It will be used mainly for watching SD and HD TV show's (including quite a lot of sport), as well as gaming occasionally (so response time is quite important) and possibly blu ray if I get round to buying a player.

I am not interested in 3D, smart internet tv's (already got a media center) or freeview HD (got virgin media HD), so I'm thinking older models might be better suited to my needs and budget.

Thanks in advance for any input!

I'm currently looking at the LG 47LK530T and the Samsung PS51D495, though there are so many TV's out there, with so many different pro's and con's, I'm finding it hard to narrow down my the choices and actually buy one!
