LG's 55" OLED
4mm thin, 16lbs, lower power consumption, deeper blacks, quicker refresh, more accurate color, smaller bezels, basically better than LCD in every way.
You'll just need to wait til later this year and probably pay $5k
Plasmas aren't bad whoever said that bit of bullshit. Typically better viewing angle, better blacks, better color, etc than LCDs, they're just power hogs. The only "downside" years ago, other than weight and power consumption, was that they would burn-in if left on a static screen long enough. Any of them made in the past few years take measures to prevent or decrease that problem...
monoprice.com is a good, reliable spot for cheap cables. Amazon or other sites you may be able to find them a little cheaper, but I'm not going to waste an hour browsing through a clusterfuck of cables to save a dollar.
