Thanks Stevelup - I wasn't questioning your knowledge - just that the guy at Keane threw me a curve-ball (I was hoping he'd know) and as I'm making a special trip - I didn't want it to be wasted.
The beauty is just sat there now in the lounge, waiting to be hooked up. It's like having a Ferrari on your drive with no car keys! Suffice to say I didn't get much sleep last night; like a kid on Christmas eve
Advice is greatly appreciated; in fact without it, I was leaning towards the LG 42PX11 for simplicity's sake.
