If it includes yearly check-ups, get it in a heartbeat. If it includes pick-up and delivery or in-home service get it, but negotiate price. Otherwise, forget it. An in-home service call on my Loewe was quoted at $250 plus parts; the thing weighs 150 lbs so I can't imagine dragging it to the shop.
Extended Warrenty???
I recently puchased a 65" Mitsubishi big sceen TV. The dealer was really pushing the extended warrenty (5 years for about $350). Are these necessary? Helpful? Do you really need to clean/realine these every year? Any thoughts would be appreciated as I can still get in on it before the TV is delivered. Thanks!
