I've used these folks (Vegas, I think) for "discontinued" batteries. Save yourself the expense and hassle of tracking down what you need locally, when you can likely get a 20 years supply for less cost by surfing the net. Cowabunga, man.
Nice resource, couldn't find the rogue mercury batteries though.
Not that I want to hurt the environment. I merely miss the kind of battery you can put in a camera and forget about for 3-4 years.
