FIRST WHATEVER YOU DO DONT BUY A TV FROM A BRICK AND MORTAR PLACE.
By that I mean buy it online.
Doesn't matter who you buy from when it needs service it will be Eds TV repair that pulls up in your driveway to fix it. Nobody has their own fleet of service vehicles for TVs.
So you will be paying their rent instead of a decent price.
Second you did not say what kind, DLP, LCD, PLASMA ?
My suggestion is to buy a SAMSUNG LCD tv with 1080p display .
Go to
BuyDig.com you will see tvs you are looking at for several hundred dollars less than what you see in stores.
I got a 46' Samsung LCD series 6 for 1100 from buydig where all others were at least 1600.
As long as you order from AN AUTHORIZED E-TAILER THE WARRANTY IS GOOD.
Some sites may be cheaper but make sure they are authorized by maker of TV you are looking to sell them online.
No reason at all, none , zero that you should buy from a store and not online.
I have 5 screens in my house all bought online.
