Dropped my Nikon d3100?

It's working fine, all functioning.
just that the dslr body has been chipped a bit near the battery cover. Now there's a gaping hole
(1.5cm x 0.8cm).It's a total eyesore, just wondering how much it would cost for the body repair

At least $100, depending on the body part and the labor it takes.

now you know not to use your camera without the neck strap on your neck
