I just had my shutter replaced (out of warranty) by Nikon. The D7000 had about 90,000 actuations on it. They wanted to charge me ~$160 and claimed it was impact damage. After I proved it wasn't impact damage (submitted continuous sequence of shots from exactly when the shutter failed showing camera didn't even move) they agreed to fix it complimentary. Thanks Nikon. $160 for shutter replacement seems very reasonable but I'm really glad they fixed it for free.
