I purchased3 television from Best Buy in October of 2007.
2 - 15" Insignia LCD's
1 - 19" Insignia TV/DVD Combo
I did not buy the extended warranty, I never have on any other TV and have never had problems with other brands.
The 19" tv/DVD Insignia combo died on the 13th month. They wanted over $200 to fix it. This TV was for a spare guest room and was only used maybe 10 times. The first time we used the DVD player it did not work and within 2 weeks the entire TV died. They said the tube died but would not support it without a warranty. 3 weeks later one of the 15" Insignia TV has died.
I will never purchase another Best Buy name brand again.
