Hi Dave, I have my reservations too, but after 6 years I really fancied a change and a slightly bigger screen + my wife bought me a BEO5 for my birthday and the MKII supports 2 STB's (for me will be cable + apple TV) so it makes the remote more useful.
£2k including a 5 years warranty and a BEO4 + he is trying to source me a pair of beolab 6000's or a 7.2 speaker for around £1k.
I gave up trying to rationally justify buying B&O a long time ago!!!
