I found the ideal GRD/GRDII case!!! The camera fits in it like a glove, fast deploy. It is designed as a cell phone or compact camera case. Nothing else fits in it, only the camera.

Made in Japan by Yoshida & Co under their Porter label -- not cheap. Porter is a designer label, like Louis Vitton. (As of last year, a few Porter bags are being imported into the US. My everyday purse is a Porter because of the quality.) The build quality is excellent, very flexible in how to carry the case with camera, or toss it into a purse. The price tag requires two people to pick it up. Pix to follow.
