Hi, I am looking for an upgrade from my 2009 white Macbook. I wanted something that has a CD drive, has decent disk space (around 320 GB+), has good RAM (4GB or 8GB), uses a good Intel chip (i5, i7...), and is relatively recent (2011-2012). For those specifications, I figured i'd get a Macbook Pro from either eBay, Craigslist, Newegg, Amazon, or some other listing or party. The problem is, I want to buy from a trusted source. Would you buy a Macbook from a trusted seller on some place like eBay (with a warranty), inspect the laptop at some location with Craigslist, or go with a trust seller, like Newegg, with a good warranty? Here is one example of what I am thinking of purchasing: http://www.ebay.com/itm/Apple-2011-...821?pt=LH_DefaultDomain_0&hash=item19fd06f45d Edit: I need something in the $800 or bellow price range, so that's why I am looking into used. Also, any constructive suggestions while going through this process are appreciated.
