LF/WTB: Older iBook/other laptop for very light usage.

[reubs]

So that my wife does not always insist on having my MacBook, I suggested we look for an inexpensive, older iBook that could be used for internet and word processing. It needs to be able to connect wirelessly, and I'd like for it to still be in reasonable condition. Reliable, working order is preferred because I'm not too tech savvy and don't want to invest a lot of time in rebuilding a computer for her.

I'm hoping to spend no more than a few hundred bucks. Is this possible?

Thanks for any info!
