I'd get a credit card that includes trip insurance - that would save you a lot of money! Or find insurance on the link through Mousesavers - they have the link to insuremytrip.com (so you really don't need the link through them, I guess) and suggestions on trip insurance.
I got a US Air card, so that covers trip insurance worldwide (so it will save us $120 or so on our Europe trip not buying insurance).
Most people will never use the trip insurance. But occasionally, something happens - like a death in the family, etc. It depends how much you will be out as well.
