You've got insurance, right ?
Don't bother with a case. Honestly. All cases do are get in the way of the spontaneity of photography, which afterall, is what leads to many of the best photographs you will take.
Asking people / animals / whatever to "hang on a minute" whilst you fiddle around with your camera case is just not going to cut it.
I own a number of Nikon DSLR cameras and lenses (none of the cheap models of either too)..... never once has any of my equipment been involved in an incident where I thought "I wish I had a case". During travel, the cameras just get dumped in whatever bag I have with me with no special padding.....all working perfectly and no scratches or scuffs to speak of (and to be honest, if you are woried about evidence of wear and tear on your camera then don't bother buying one in the first place).
Its a piece of tech kit, not a one week old baby. Get over it, get out there, and start shooting.
Updated to add :
Don't forget about the sheer rate of depreciation that tech products enjoy. The loss in value caused by any wear and tear will be vastly outweighed by the prompt obsolecence of the technology in your camera.
