Hey Terri, After going through a couple of months of research we ended up getting a Mitsubishi WD-57731 57" 1080p DLP HDTV. I researched online and went to 5 different stores spent quality time checking out every TV they sell. For us the Mitsubishi was superior especially with bright rooms and a dull view or glare. The key to figuring this out was to have the sales guy turn on the light in the TV viewing room, it was amazing to see poor quality viewing on the majority of the screens in the room, the Mitsubishi angle and view with the lights on and off stood out for us.
Yes, I bought the extended warranty. I bought my first large screen Mitsubishi 12 years ago and a 5 year warranty, after moving 2X I was grateful for the extended warranty. The tech came out tweaked the TV and all was right and I didn't pay a dime. The DLP warranty we got includes 2 free bulbs.
Good luck!
