Vincent calibrated my B7 a while back and to be honest I don't see any difference at all. I'm shocked at how many positive reviews his service gets considering most new high end TV's are very accurate out of the box, especially when put in the ISF/Cinema/Professional modes. He's a friendly guy and everything but like I say I don't notice a difference compared with the ISF Night mode I was using. That's £350 down the drain for little over 60minutes of pressing buttons on a remote control (what a hard life). Save your money and put the TV in the most accurate picture mode because the colours will drift after calibration anyway.
