Be VERY wary of how much room these things take up (if you are not wall mounting). Mine is 42" but with the glass stand (which also cost up to £500 for a decent one) they do end up taking up a fair bit of room....... the wires as well are also a pain in the ass, especially if you have a Dolby Digital set-up as well.

Just to give you some idea (and my living room is'nt really that small).
