I found a hard case for my Casio EX-Z750 at sears.com. If you follow this link it will take you right to it:

This case is perfect for me. It's not big and bulky, and the camera fits snugly inside. There is a small pouch on the inside to carry an extra memory card. If you are planning on carrying an extra battery as well, I would suggest using another case, as this case does not have enough room to carry an additional battery. I hope this helps.
