I have a rider on my policy that brings my coverage up from the standard $3,000 per catagory ($3,000 electronics, $3,000 jewlery, $3,000 firearms, etc) to $10k for a couple categories (jewlery and firearms). The total amount of my riders is just a touch over $25/year. I have USAA. If your agency doesnt offer something similar, or it is crazy expensive, find someone else. If you qualify for USAA (current/retired military, some connection to the military) I would start there. They have always been very fair, and have no problems covering all of the obscure stuff I am into.
