I needed to up to 4 cores for business so I've been on the lookout for a a refurb or used, for a few months now. This is the best deal I've ever come across. http://www.ebay.com/itm/131643187635?_trksid=p2060353.m2749.l2649&ssPageName=STRK:MEBIDX:IT Now, it is supposed to be in perfect condition and 3 charging cycles indicates that it was almost never used. So that is fantastic. However, I had assumed it was still in warranty, seeing as though it MUST be only a month, or so, old. Come to find out, it is out of warranty. Needless to say, I am starting to feel a little insecure about this purchase. There are some refurbs on Apple but at 2.5ghz and 512gb storage, for 2400 after taxes. I'm not really dead set on the processor speed, but the TB is a necessity. Also, I prefer the mechanical trackpad, as I am faster working on it, when I need to be mobile. I'm not very fond of the new one, so a 2014 was also a necessity to me. Without any major debates, or strong opinionated "needs vs wants" discussions, would you call this a good buy, or a mistake, and why? Thanks. Oh, and there is a 3 month warranty with the seller.
