My job requires that I travel with a set of tools (no jokes, please

) that have to be checked. So, I'm looking for a good tool bag that's big enough to hold an electric screwdriver (not a drill), a bunch of widgets, and an assorted set of screwdrivers/wrenches/etc. It had to be durable enough to withstand being checked and not fly open, yet fashionable enough for a young gay man.
So, to all you traveling repairmen/women out there, is there a bag or line of bags that you recommend?
