I got a refurb Apple G4 PowerBook last month because, for a bunch of reasons not worth going into here, I didn't want to switch to the newer Intel-based models after an FA spilled milk on my old one. (Details in the AA forum; suffice it to say that they paid with no pushback and no hassle.) Has a one-year warranty, same as a new one. No way of telling it from new when I unpacked it. (My previous one, quite similar, was purchased new, so I knew what I was comparing it with.) So far, after about a month, no problems.
