It's not so much the eating the batteries as the recharge time increases dramatically. Anyway found it today. Phoned a local Canon Professional Photography dealer and was told it was discontinued. Phoned my buddies at waltersphotovideo.co.uk and they're ordering one from Canon and I'll get it next week. (They're not really my buddies but it's where I got my camera etc from. Good service, prompt delivery, well packed and competitive pricing. I'd recommend them)
