Sorry to hear that. Robberies cause more victim pain than the law allows punishment for. I hope you get lucky and find the equipment. If you have the serial numbers, send them the the police and then start scouting out the local pawn shops. You will probably have to pay the amount the pawn shop paid for the items, but it will be 10-20% of the value (thread here)
