hi guys.. I'm using nikon sb600.. haven't use the speedlite for quite a while, when i want to use it yesterday, it can't be turned on. when i check the battery compartment, realized i didn't remove the battery during the last time i used it and the battery has started to leak and damage the battery compartment. can you guys suggest where i can send it for repair and how much does it usually cost to repair it?

Thanks!
