OK got the 40" in the end, wife wasn’t keen on anything bigger but she let me get a soundbar as a bonus so ended up with this one http://www.amazon.co.uk/Sony-Channel-Wireless-S-Force-Subwoofer/dp/B00HRW0ED2/ref=pd_ybh_11
We also lost our sound system when I dumped the PC with it’s 5.1 surround system so the soundplate also has BT so we can play our music through it as well.
Once I get a new floor down I shall try the 5.1 system.
Here is a pic, very pleased with it, just need to get some time to stick some decent movies through it.
Thanks for all the advice and thoughts
