Hi, What should I ask/look for when buying a used MacBook Pro? Found what seems to be a good deal on a Late 2008 15" 2.4GHz 4GB with an aftermarket 128SSD for around a grand. Have a friend who is rather Mac competent and he indicated "If it boots, you're good." What are your thoughts? Thanks Edit... Or would a refub from the Apple store be a better purchase. The 13" are around the same money unless I go nuts and splurge for a 15" with an i5 chip.
