i bought a 15GB ipod(non-click wheel) from the refurb site last december. It worked great. Looked brand new. The battery life was only about 4 hours, which i didnt like, but it worked fine. But, i did have to ship it back in for repair about a month after i got it. It locked up on me one day and once the battery died, it wouldnt turn back on. I filled out a RMA on apple.com, got the pre-paided return box the next morning !😱 Got it back about a week later. I think they just gave me a new one, because it didn't have any scratches on the back. Other than that i would recommend the refurb site as well.
Im about to buy a 14" ibook, or a 17" imac G5 off the refurb site hopefully this saturday. So by wednesday i should have a new ibook, or imac, only time will tell.
