Looks like my old 27" TV is starting to go. (Its 18 years old!) I see that Plasma TV's around 42" (720p resolution) are selling for less than 42" LCD (1080p resolution). To me, it looks like the plasma sets have better picture quality (colors and contrast) than the LCD, even though they aren't "full HD" resolution. Does it really matter for a 42" set? Sales guy said that image "burn in" are not an issue anymore, and the life of the plasma displays are the same as a CRT. Would I be making a mistake? If I buy a new set, I don't really plan on buying another one for a long time. Anyone have any bad experiences with plasma TV's?
