Plasma or LCD?
A friend who's a TV Guru told me that Plasma is only good for about 4 -6 years. That they burn out after that. Also Plasma has issues if the Sunlight hits it at all at any angle.
I have VIZIO (32") and Insigna (52") LCDs Flat Screen.
I 've had them both going on 3 years now...like them both. Insignia is Best Buy's store name brand.
