Aftermarket Warranties?

I'll add this: Some folks have them and claim to already be money ahead, others have them for the life of the contract and never use it, and still others that have one have just about all their claims denied for one reason or another.
If you're set on getting one, put the names of all the different ones into a hat and draw one, have just about as good a chance of getting a good one as you would from someone here.
