I have the 65" version paid a little 1300+tax so no brainer. My suggestion is check the web for ideal picture settings, I think calibration is a waste of money, when you can do the research and do it yourself.
You will be happy with this TV, I have always had Sony TV's I sold my XBR4 to a coworker for $200.00 great LCD TV that has been working perfectly since 2008 I have the 850C and another 55inch Sony in the bedroom.
