A caution about laptop refurbs.
I bought an ibook back in the day. Generally a good machine, but the battery died in about a year. The replacement battery is still going strong even now, four years later.
Not taking my own advice, I bought a 2.16 MBP refurb. Nice clean machine, but a problem with the Superdrive. It's been replaced with a new 2.2 machine (after much discussion with Apple) which, so far, is perfect (including the LCD screen, thank you)
I also had a similar battery life problem with my ipod.
That said, my refurb Imac has never given me a second of trouble and I didn't even get apple care for it.
best
