Ok-- so we took the plunge and bought a 46" Samsung Touch of Color LCD 750. By the way -- picture is absolutely fantastic!! Almost 3D if you know what I mean.... anyway the Best Buy guys said the TV needed to be calibrated after 100 hours of use to get the best picture and save 50% on power costs. Now the picture deal I'm for sure a bit skeptical about, but they said that without calibration it would cost about 16 cents an hour to run and with calibration about 8 cents an hour resulting in about 150 dollars a year saving. Anyone heard of this?? or knowledgeable about whether they are just blowing smoke? It costs 200 dollars to do the calibration... so if they are right its a no brainer. Also what about extended warranty? We usually NEVER do warranty's (they are all profit and commission) except for our apple computers, but we are new to this big screen thing. Thoughts anyone? We just don't want to be ripped off an additional 500 bucks, but don't want to cut my nose off either..
