Anyone know where is a good place to get replacement DC battery?

I've checked Blacks, they want $69.99 + tax for a authentic fuji battery.
if there are generic brands which is like $40 difference, i really don't mind.
i've found some on ebay for $30 and it comes w/ a travellin'
charging kit too!

NEwayz, anyone know where i can find it locally in TO? PMall? FMP? or the source?
