I need your Input: LED TV versus Plasma TV

[Angry_Pirate]

Currently have a Samsung 46" LED TV it has been a great TV and has been on 24/7 for the past 4 years to keep the dogs company when we are at work. The TV has some bad vertical lines across it and the internet research I've done suggest is maybe on its last leg.

Anyways the wife and I have been talking about getting a bigger TV for our living room for when friends and family come over and now it looks like we will be getting another TV to replace the Samsung. We may end up getting 1 Plasma and 1 LED from Costco since they have a 5 year coverage plan. I'm looking at Vizio's for the LED.

I hear these new Plasma TV's are better than they used to be. Just looking for input on reliability and picture quality from Plasma and Vizio LED owners.

Thanks!
