If you want to spend some extra money go for a good plasma tv.
They last long enough.... 30,000 hours and more... if you use it 5 hours a day it'll work atleast 15 years.... nobody keeps there tv that long.
There are quite some brands that have an external tuner which u can place on a stand and the tv on the wall. All cables will go to the tuner.
Here's my pioneer with external tuner. ( wires are still a mess )
It's a 43" but I think I'll get the 50" soon.
