One other thing I just thought of. When I traveled out of the US with cameras and stuff, I always took my cameras and junk to the airport and went to the Customs area and found someone to inventory my stuff and give me a piece of paper saying I OWNED this junk BEFORE I left the US. That way there can be no issue bringing it back into the US. I know, I know, paranoid, but that is the way it happens at my house.
