Our older 32" flatscreen just wasn't cutting it so we had a look in the sales and came up with two options.
A 44" LG (we already have a 48" LG in the bedroom and I always like to stick with one marque as the remotes are usually interchangeable) or a 40" Samsung which could be connected directly to the internet. Both cost* the same.
Size is not always important- we plumped for the smaller but more up to date option and it fits in perfectly now that is linked up to the X Box.
*THB 13 000 in this case- a shade under £300 plus beers on top.
