I'm getting my new macbook pretty soon (waiting for some money back from the tax office first) and it struck me that I hadn't really checked out eBay!

Has anyone ever bought a refurbished/2nd hand mac and if so, what was your experience?
I could pick up a 160gb white macbook with the 2gb ram and Superdrive for around 550 and I think compared to the 717 I'd pay for a macbook (with student discount)

It would mean I could buy it pretty much straight away and also I'd save a bit of money for perhaps a new lens or something for my camera

Just don't know if it's worth paying the extra 200 quid AND waiting ages for what's essentially the same macbook but with a warranty
