It's all good to discuss specs but no one has asked what soft of room it will be in and what you will be using it for?
If it's in a loungeroom, like ours is (we have a 50" Samsung Plasma) does the room have a lot of sun light? This will affect your over all viewing experiance.
Brighter rooms are better suited to LCD, Sadly, we moved into a new apartment and every room in the apartment has massive windows and full of sun.
I have noticed the plasma struggeling if you like during the day, seem's dull and lifeless.. In my room, again, totally sun filled, I have a new 42" Toshiba Regza LCD and it's beautiful and bright even on the sunnist of days.
I also game a lot and feel that LCD is better suited (to me) then what my Samsung plasma is.
LED is great and I would love to get something LED it will drop in price soon, If you need something super thin and space is a huge issue then LED would be a good option, if you a bit of a tech geekand you want the latest, get LED lol
If you aren't and dont need the newest and shinnyest thing, look at LCD
