I'm thinking about getting some cases for photo gear, and I'm considering Pellican. I like their idea of hard plastic that's waterproof with replaceable O-rings. They have padded inserts that are flexible for holding a lot of different types of gear, lenses, etc. Their gear can also be locked for airline travel.
I don't know much about cases. Is this good quality stuff? Does it break easily? Can it handle heavy gear, like a couple of Dyna-lite M2000 power packs? (I would use some padding with the power packs.) I'm wondering about other photographers' experiences with Pellican cases.
