I have a dilemma and thought some of you fine folk in the neighborhood would have some advice. My little MacBook pro from 2009 is dying. Just learned the hard drive needs replacing at a cost of $220. I'm torn between repairing it and finding a newer used one. Re-PC only has one and it's 5 years old and $660. Any geeks out there with an opinion? Advice where to look for a newer used one?
