Hi, i know nothing about Plasma, except that it looks good, its thin and i want one. I looked at the Panasonic 42 inch one, that isnt 720p native, as thats way too expensive for me to afford. My question is, is there any maintanence required for a Plasma TV, or is it just like a regular TV. I know projectors have a bulb that need to be changed, what about for Plasma TVs, will they last for years on end like CRT TVs? We had a Sharp that lasted like 12 years.
