Here is the room: With that much light do I want Plasma, LCD, or LED? While at Costco, I saw this Samsung. 55 1080p 120Hz LED Edge Lit LCD HDTV Resolution: 1920x1080 Dynamic Contrast Ratio: 4,000,000:1 $1999.99 The picture looked fantastic. Do I really need to spend $2000? I was hoping to be closer to $1200 - 1500. Any others you recommend? Important features? Brands to avoid?
