I got a Lowepro Apex 60 for my other half's G9.
Fits very nicely with room for a spare couple of cards inside.

Got one initially for my G11 but found it a bit bulky. Bought a Canon G11 specific case in tan - not cheap, but very retro and it is much admired by others! Fits like a glove

The same case on ebay will cost you £20.. nice cases as well, I had one myself.
