Just wanted to throw a subject out to everyone about batteries. On my previous camera (an old Olympus e10) I was using batteries at an alarming rate and im my search for a solution I came across the Digipower DPS-9000S. This solved my problems, I could take about 150 flash photos with the built in flash before I had to recharge. So lastnight I tried it on my sd10 and it works like a champ. It plugs into the external power plug and is auto setting for voltage. I will update as I try it out with this camera, not knowing yet how power hungry it is.
