Hey, my friend is ready to dump his 2011 MBP to go Retina. If he sells it with this, on eBay, what would be a good price? 2.3 GHz i5 Processor 8GB RAM 256 GB Solid State Drive Has Windows 7 Professional 64 bit OS X Mountain Lion iLife suite Office 2010 Enterprise on the Windows side and Office 2011 for Mac It's basically in perfect condition, and has the original packaging. All materials and disks included. Can I get four figures on this?
