Any kind of insurance is like that....cars, disability, medical, life. If you don't end up needing it, it's a "waste" and inflates the cost of whatever it was covering. If you end up needing it, it can save your ass.
It depends on your financial situation. If something happens to it and buying another ruins you financially or mentally, then buy the insurance. If you can afford the hit, then maybe take your chances. Just limit your exposure by taking care of it and not throwing it around/down. I can afford to buy a new one (though maybe I wouldn't at those prices!), so I generally don't buy insurance on these kind of things, as I am more bothered by continually paying for something, LOL.
I suppose you could just start out with the monthly insurance for peace of mind, then when you get past a certain point in time, quit paying for it...
