Hello I am going to be purchasing the Retina MacBook Pro "15 in June/July when Haswell comes out. I would like to know if anyone knows about how much I would get for this machine with the following specs. It is in good condition with slight scratches due to wear and tear. 2009 13" MacBook Pro: - 2.53 GHz Processor - 8GB Ram - 250GB HDD Preinstalled with legit Mountain Lion, iLife '11, and iWork '09. Thanks. I will be selling it on eBay when I get my new one.
