I know you said you weren't a fixer, but if you were, and if you were brave and/or crazy enough, you could try
this.
Supposedly-working logic boards show up on eBay regularly, but they typically cost more than sending the iBook our for reflowing.
Lars is right to question the longevity of the fix, either by sending it out or doing it yourself.
OWC is selling working iBook 800s for about twice the price of the board itself.
My sister (not the most reliable source of information) told me that a Mac reseller offered her $75 for her iBook 700 with the same problem for use as a movie prop. You or someone else could part it out. You could make like Denise Richards and knock it off a balcony.
Even with an essentially useless Mac, you still have options.
