You both are missing the most important word.
Quattron.
Seriously, take your PS3 to Best Buy, plug it in, and you will rejoice. No 3D but I believe they still are the only manufacturer to make an 80 inch.
I bought my 46 inch December 12th of 2010 for 1050, regularly 1499. I bought the warranty, and when I checked in february, they said I could get the replacement model on warranty or 1,000. If you wait for a deal, you can't beat it. Over a year old, and I've lost 50 bucks.
It seems over rated, and was annoying at first, but seeing the yellow in the screen does make a difference. I am partially color blind and a bit into photography, and I spent a long time barking and complaining about how nothing properly shows an image. Mobile phone screens, my dSLR screens, and every tv. But looking at images on the Quattron. It's another world. On the most beautiful day, I'll close my blinds behind my tv to shut out the world and play planet earth, or look at images.
The wiring in most stores does not do it justice. I implore you to test it out. I've never met someone who has used my television and not decided to get a Quattron as their next television.
(Although I use good HDMI cords, and always blu ray or .ts, which may have an affect.)
Oh, yea, Quattrons are usually LED, I believe they are all LEDs, but I do not know this for fact. FYI, because no other screens use yellow, you can only see the difference in person or through print, such as a picture. I also suggest Best Buy for price matching, and for their black tie warranty. Well worth it. For 249.99, if anything goes wrong in four years, they replace it free of charge for the same model, or it's value. If it's not available, they upgrade it.
Plasma's are good, and the burn in is gone, and they are a bit more eco friendly, but they get VERY hot, and I've been told the more one uses them, the shorter time they last. I do not know that second part to be true, just the first with the temperature.
Whatever you do, don't go LCD. As in, flourescent back lighting. Go LED LCD. Price have dropped enough, I don't know why they even sell regular LCD anymore. OLED will be nice, but you have a few years before they are out and reasonable.
I am by no means a master, but I spend approximately 7 months searching for my perfect tv, so I have some knowledge. If you want to ask me something, I might know it, so PM me. (I usually forget to re look at threads)
