if you're not planning on having your camera insured, then yes, I'd say it's definitely worth it. Otherwise, it depends on your policy I guess.
I hand lengthy conversations with both B&H and NEW (assuming you're talking about the sagemax plan), and you're covered for nearly everything short of the camera being lost/stolen.
How bad would it suck to hold the camera in your hands after long last, then a stray dog grabs at your leg causing you to drop the camera, completely destroying it. Would probably put you into a state of depression if it wasn't covered. Paying less than 10% of the purchase price for peace of mind seems worth it to me.
