Yeah, they are overpriced. But Brukus has a link to a video that shows how to remove (steal) locked hard bags with needle nose pliers, it takes a couple turns on each pin and it's done. I keep some valuable stuff in my bags (GPS, I-POD, etc). When I saw the video, I spent the $30 bucks. Easy install and peace of mind are worth it to me. I also bought the seat screw, replacing a seat is costly, by comparison the seat screw is cheap, especially when you can remove the stock screw with a nail clipper. I hate to sound like a Brukus salesman (I'm not) but there are creeps out there that steal seats, windshields, bags and almost everything else off our bikes. A few years ago a friend and I were at Sturgis and came out one morning to find his detachable windshield and hard bags gone off his Road King. BTW really, really good thieves HAVE the Burkus tool, but most "snatch and run" guys just move on to the next bike rather than mess with the screws, locks, and security systems.
