thats weird you say that cause every recent source ive read has said that plasma tv's power consumption is now on par with LCD tv's, and most plasma tv's are energy star rated the same or even better than most LCD's. at worst a plasma tv is going to cost you about $20 more a year in power... but LCD/LED tv's are usually $200-400 more for the same size screen as plasma... do the math. you arent saving anything by paying more upfront for an energy saving tv...
@ wt: i dont own a tv, but ive been doing a lot of reading. if you're going 50+ inches on a TV and using it for gaming and movies, then plasma is the optimum choice. plasmas have the best response times and the best dark levels. video games and movies THRIVE off of darks, thats how they get HD video games to look so good, with darks. i remember you told me that you dislike the soap opera effect though, where the image looks like youre watching a play or something. plasma tv's operate at 600hz compared to 120hz for most LCD tv's, so you will definitely get that ultra clear soap opera effect that you said you dislike if you go for a plasma and watch a lot of tv. LCD /LED tvs have the best brights. LCD / LED = best for watching or playing on in a room with a lot of light, lot of windows. plasmas = best when watching movies or playing video games in a dim room, or in the dark.
LED tv's are pretty expensive right now, LCD is the most common route that people choose at this moment. LED tv's right now are just LCD tv's that use LED's for backlighting, to save electricity. which is odd because they usually advertise that they have the best brights and the whitest whites.... then you basically cancel those features out by using the energy saving LED backlighting which cuts down the brightness to use less power.. LOL. i think you actually sacrifice some screen quality with LED tv's at the moment, unless you're buying a top of the line one for $2000+.
all in all you just got to compare them in person with your own eyes to see what you prefer. no matter what youre going to get a great tv. i prefer plasmas though, because playstation 3 games seem to be dark, movies seem to be dark, and plasmas are perfect for them. also i like the soap opera effect
