Where can I find the lowest priced Canon OE LP-E4 bats and charger?

Hey everyone;

I recently picked up a 1D MKIII but it only came with the A/C kit as its only power source, no batter, no charger.

Where is the best place to buy OEM canon batteries and chargers?

When it comes to chargers is it ok to buy a third party charger or is there more risk for overcharging, undercharging or shorting the battery?

Thanks everyone.

I should also mention that I want to get them for the lowest price, dont mind if they are used as they last forever it seems.

Ok I just picked up a new Canon OE LC-E4 charger for $119, Ya I know, a super awesome deal

Now I just need to find one or two LP-E4 batteries.

Does ANYONE know the best place to buy these OE batteries?
