From what I can gather from the postings on the forum, I would think that you would be better off taking your money and sticking it in the bank and saving it for when you need it for a repair.
Also remember that it's not really an extended warranty, but rather an insurance policy with LOTS of fine print. It's a huge profit maker for the dealers.
