Nikon d3100 cracked screen?

My nikon d3100 has got a small crack at the bottom of the screen. It doesn't affect the performance of the camera but just doesn't look very nice. Its about 1cm long but is not cracked on the outside but seems to be cracked under the glass. Do you think I should get a new camera body? How much would it cost to repair?

If you get a new camera body you're wasting money.

The screen can be replaced by a competent technician. A new screen for a Fuji was about £25/$50 plus fitting (I'm competent technician so I fitted it myself and didn't charge me) and a Nikon one woudl probably be more but still way cheaper than a new body.

You can have the LCD replaced at a cost that is lower than a new dSLR. Ask the store you bought the camera from. They should point you to their authorized service center.
