Television recommendations please
Personally, I would buy a mid level plasma now and consider OLED when it drops in price.
I'm not a big fan of the current LCD/LED technology. I hate the soap opera effect and the blacks are not true enough for me. I watch a lot of sports and plasma handles motion much better. My Samsung plasma has anti-glare coating that really minimizes glare, pretty much making it a non issue.
Fair warning - you will probalby be told by the salesmen at big box stores that LED is the only way to go. I think this is because margins are typically higher and the technology is a little newer.
Don't take much stock in the picture you see in the store for your comparisons. Your perception is very much influenced by the calibration (or lack thereof) of the televisions and the lighting in the store. Are you really going to watch the TV with 20 ft ultra bright ceiling lighting? Are they both being fed the same source? (I wouldn't be surprised to see LEDs hooked up to HDMI sources and plasmas hooked up to s-video sources.)
Lastly, I would recommend reading avsforum and watching cnet reviews for more in depth analysis. You can get more information about failure rates and common problems from enthusiasts.
