Any AV people on here. Need some advice on a new LED TV

[Gman]

Plasma displays produce more heat than an LCD. I would imagine the short lifespan for those 2 plasmas was more related to the installation in an environment not suited to the technology.

Does anything that lights up and makes colors suitable, or do you want the best picture experience? This is like comparing ground turkey at the price of a whole steer vs. a prime ribeye. The F8000 being discussed here runs about $2500 for a 55", $3400 for a 65". The last 55" Panasonic Plasma set I bought ran me $600 on a special at Costco.
I don't run my home theater 24x7 and most folks need to sleep at some point. I sure wouldn't want my subwoofer waking me up all night.

Another question is whether or not you need 3D? Adds a lot to the price but content is limited. I also don't like wearing those stupid glasses or dealing with the headaches.
