After a lot of reading I think I have narrowed my selection down to two sets, both Sony Bravia W series.
The first set is a Sony KDL-40W4000, reviewed here
The second is a Sony KDL-40W4500, an uprated model of the first set and slightly more expensive. The review for this one is here
I am leaning more towards the 40W4500, but would like an opinion from someone who actually owns one or knows a lot about them! Ignore the price at What Hi-Fi? the sets are way cheaper online.
