Anyone have their system insured?

I was out of town over the weekend and during that time we were hit with some severe storms. Many neighborhoods were completely flooded with reports of nearly submerged basements. My system happens to be in my finished basement, which has never flooded or even leaked. However not being there to check still concerned me. Thankfully everything was ok when I returned.

For peace of mind, I was considering getting my system insured. Anyone else have their system insured? What is the best way to do so, as a rider to your homeowners policy?
