I will be getting one before my stock one expires.
Warranty story:
A few years ago I bought a new HD. (financed)
The salesman asked me if I wanted to buy an extended warranty. Of course, I said no.
He then told me that they had a reduced interest rate if you purchased even one years worth of extra warranty. (arount $700.00)
I was amazed when they recalculated everything my monthly payment was about $5.00 less then it was without the warranty.
I have used it one time to the extent of about $1,600.00.
In this case, it has paid for itself.
Tread lightly.
