I don't mind if it gets banged around and contrary to what some do (plaster them with stickers) I'd rather let its bruises speak for itself. Hard to look for a comparable clam shell type that's a bit more affordable. Not a big fan of zippered luggage as well although I may not mind it for land trips (which I do a lot).
Let's see.. what I'm actually looking for right now is a lightweight vest that doesn't scream "I'm a photographer". Not an easy thing to do given my workflow in the field (which is a work in progress in itself). And, yes, I want to look decent as well :p
