I have several pelican cases that I use to haul electronic equipment and other gear for boating.  Given that I sometimes fly to where a boat is located, the cases have to withstand shock from baggage handlers, and protect the contents.  These cases with the foam insert do both.  They are also somewhat watertight depending on how you pack them and the integrity of the gaskets that surround the lid. So far they are the best case I have found for use in a rather hostile environment.
