I purchased my Samsung 46" 1080p LCD TV in 2007 for $3000 AUD. It's still going strong now. The only single thing I miss from it is a lack of HDMI-CEC support.
We have a similar plasma model, which we got for free because the owners were upgrading to a new one. I love how it doesn't do anything except display signals; we pair it with a Chromecast for most things. Of course, the electricity cost of a plasma TV adds up over the years...
HDMI-CEC is great and works flawlessly if the equipment you have supports it, at least in my personal experience. On some older equipment, not all of the functions worked though. For example, my old TV could uses CEC for volume and power on but not power off. New TV does it all perfectly.
