been researching similar - one issue on size is that the older 40" ones would have a frame around the screen that would make it look much bigger/more bulk. Most of the latest have little surround frame and are thinner so bigger screen size actually looks like a smaller bit of kit

As people will always say hunt down a local Richer Sounds

I narrowed it down to these
