Esther my advice would be to pay the extra for the extra 5 years of warranty. I know it's $500.00 but the way things are made now days, I would rather have the protection than have to foot the bill for another unit.
I know all of the appliances that we install now are being made cheaper and cheaper and warranties are getting shorter and shorter. Just for your protection, I think it'd be worth it.
