Crumpler are very nice... also check out Kata bags. They also sell body armor if you feel like going to a war zone to try out that VR lens..!
I tried to find a Kata bag that fitted all my video stuff (including the underwater housing) and yet was still small enough to be considered carry on. I got close, but didn't quite get there. I think the housing is too big to go as carry on.
But the bags are very well designed & made;

I should also say what I use for my camera gear...
I have a Pelican camera bag. It's nice in that you can get into in through the side or the top depending how you have the dividers laid out inside and it fits into the appropriate Pelican hard case for time when you need more protection, but you don't have to have the weight of a hard case when you don't need it (Pelican do sell divider sets for their hard cases). Can't find it on Pelican's site, so maybe they don't make them any more, but I found it here;
