Just a quick tip, if like me you like your gear secured while travelling around, The Pelican AIR case 1525 is a perfect fit. Just get the four layers foam, and only cut through the second one for a tight fit. Once the lid is closed, nothing moves around. You can also cut a space out of the third layer for the power cord if need be.
Costs : around 150$. More expensive than a soft bag... but this thing is built like a tank!
