I've used Pelicans for years with the military, but my money going back even farther has gone to SKB cases. They're cheaper, lighter, and the company is great to deal with. They provide insurance against damage or theft of anything transported in their cases. They upgraded a number of years ago to quick-change locking mechanisms that are user replaceable, and will fedex you out replacements for free if you get somewhere and the locks were damaged in transport (TSA pried mine open with a screwdriver rather than open them with their TSA key).
