I just asked my State Farm guy about this last week! My quote was $240 a year (we valued it at $6000), we are in California. He said if it is lost than I can claim the loss on my homeowners but it would be chargable thus raising my homeowners rates so we were thinking about the additional policy as well. I asked my animas rep and she said they are really good about replacing the pump for breakage and that breakage is pretty rare because it is made pretty durable (made out of motorcycle helmet material). We are still trying to decide if we will insure it or not.
