Loren: The best place to look is eBay -- I see logic boards there all the time.
I've always avoided new Apple products, buy them used (currently using a rather tired G3 beige and a Wallstreet Powerbook).
Have you done any research on the G3 700? Apple products can be somewhat tempermental, and the fixes are sometimes software versions rather than hardware, or improper configurations.
What has been going wrong with the iBook? Peter
