Best choice we could find for this room
Date:August 31, 2011
Best Features: Sleek design
Cons: getting service from the cable company to properly set it up - Cable company stinks!
"We only stay at 4 or 5 star hotels and they only have LG TV's in the rooms so that kind of means these hotels have done their homework as to what brand is the best in service and quality. Therefore we decided to buy this brand for our home use also."

LG37 720p
Date:August 26, 2011
Best Features: Nothing
Cons: Everything
"I bought the LG37 720p two years ago. After owning it for 6 months it started shutting off and starting back up in the middle of movies. Also, the back light would dim periodically during all programming. Best Buy came out and replaced everything inside the TV, but only after I complained to multiple people (One of which was VERY rude) in the store and eventually threatened to boycott them. All because I did not purchase the extended warranty. A week ago the picture went black and all I could receive is sound. A repair man came out and just gave me an estimate for $487. I think I will purchase another brand TV at another store instead. I've just about had it with BB and will definately avoid any LG products. Buyers beware, do your research before you buy."

Great HDTV set. Easy to set up and install.
Date:August 24, 2011
Best Features: Easy to set up. Swivel base. Great picture.
Cons: Nothing.
"Great HDTV set. Easy to set up and install. Gives excellent picture. Sits on swivel base which can be adjusted to location of viewer in room. Replaced an old 21 inch set so we have really enjoyed looking at the "big picture." My grandkids love it! We have had no problems with it. Recommend it to anyone who is making the jump to flat screen HDTV."
