Yeah, the cheap battery should be fine for most things. Can you tell me where there is a 60 or 80GB IDE HD for that cheap?? xD The cheapest I have seen was the $38 dollar one I sent, or whatever price it was. Although, one that's not said to be for the PowerBook G4 is probably cheaper; I just searched for "PowerBook G4 HD" so as to be sure I was getting the correct thing.
