State Farm has a policy called PAP (Personal Articles Policy). I would highly recommend calling and getting it. The lowest price a year is $60 (least in Mn) so you can add some other items like electronics, cameras and jewelry. I pay $5.50/Month for my MPP, DSLR and my DSLR Lenses.
This includes $0 deductible and covers you in case of a crash, lost or stolen. It won’t cover natural wear and tear though.
