G15 Horizontal Case?

I'm using my new G15 in my previous favorite P&S bag, the Think Tank Modular Pouch.

I'm looking for a case that allows the G15 to ride horizontally. The power button is a little bit too easy to press with the camera positioned vertically.

So far, I've found the Kata DV-410.

The Mountainsmith Focus II is also a possibility.

Have any of you found anything else that works well?
