It was a Targus case, and I finally found it on their website. The one I'm thinking of for the FZ10 might be a slightly smaller model than this one, but like I previously stated, Targus is notorious for quickly "moving on" with other models on their website when older models are still in stores (and will be for quite a while).
Here's the link:
Targus DBUV02 Camera Case
FYI, it's $19 as BestBuy. Be sure to click on the option under the picture for "More Images". It shows the "hidden" pocket I mentioned that would be good for the charger and cables.
I'm still tempted to go and get one for my FZ1, but I think my wife would kill me if I came home with a 5th camera bag! I currently have a big gadget bag for everything, a mid-sized Targus video bag that can hold my video camera and the FZ1 (and most gear), and then I have my Targus briefcase style case that holds all FZ1 related gear perfectly, and then I have my Coleman camera case that just holds the FZ1 and a spare battery/SD card. I just can't seem to find that "right" case for the FZ1!
