LCD's picture quality are just as good as Plasma's IMHO.
The thing that swayed me on my recent purchase was how much electricity Plasmas eat, 2-4x as much!
i bought an LG 47sl80 in March, i fucking love it!
47", 1080p, ultra thin, 240hz
it's got every option imaginable, and is as thin as an LED, while not being one (only 1 inch thick).
