[iBook] battery for G3?

[Don Hinkle]

We have a 12" G3 iBook that's been giving good service, but the  
battery can't hold a charge longer than 30 minutes before shutting  
down. I used to have a second battery but can't find it anywhere...  
Where's the best place to get a good (i.e. less than $129) price on a  
battery for this Machine?
thanks...
