Well my 2012 MacBook Pro is officially dead. It's suffered the GPU problem that has claimed so many. I'm just not paying $800 to fix it. So I need another one. Obviously I don't want anything that has the same issue. Problem is money, I'm pretty broke at the moment. I'd really prefer another 15 but I don't know if it'll fit in the budget, which is as cheap as I can get away with. I'm open to refurb. Looks like the cheapest apple has is a 13" retina but it only has 128gb hard drive. Are they standard or proprietary? Any other source of quality refurb?
