Do you think, In that case, add on warranty is required to be purchased ?
Don't forget many CC's offer a doubling of the manufacturer's warranty up to a year. So 1yr = 2yr. (most Visa's, some Discover Cards added it last year +, and Amex cards, as well as a few MCs).
From lots of reviews AMEX seems to be the best (easiest to deal with & best response).
Discover is pretty new @ it so IDK how they are handling it.
Visa seems to be a jump through hoops but workable.
