fyi - $28 battery for Canon G1, G2, G3

I was considering another back up battery for my new G3. I already have one extra, purchased at battery barn for $44 (1500 mAh). This one seems to be an excellent bargain at $27.99 (1300 mAh). It will not quite as long, but at $16 less, it is still a bargain. http://www.sterlingtek.com/ln03-canon-bp-511-dlc511.html

There have been times when I am on vacation, that I have just squeeked by with only having 2 batteries, as I'm not always able to recharge.

p.s. mAh only stands for mili ampere hours, indicating the length of time that it should take a battery to discharge. I take this as a general guideline only, not a hard and fast rule.
