I am considering buying a MacBook Pro, with Best Buy having a very nice sale right now, I am wondering if I should buy the $999 128GB MacBook Pro 2017 or get a used, but in great condition 2016 256GB MacBook Pro off of eBay. Is the 2016 worth considering for the extra space? Or is the 2017 worth considering because its the newest model and would be new instead of used.
