ibook 1ghz white..decent replacement battery and possibly a hard drive

[Kraniac]

My son's ibook needs some care....

Anyone have a source or brand for a reliable replacement batt for an iBook 1ghz 14" white..?

I'm assuming the batt replacement is fairly easy??

Also, is it a pain to upgrade the hard drive on this machine? Never cracked open an iBook.

It's got a 60 gig but I'd like to install something bigger.
