I have the 15" version of that same computer. Mine is also a refurb; I sprang for the larger screen and a Core i7 rather than a Core i5 processor.
This machine is amazing. It is hands-down the best computer I've ever owned. I maxed out RAM (16 GB) and put in a second hard drive (by removing the DVD drive), and it's become my workhorse. It goes everywhere with me, and it's absolutely a fantastic computer. I recommend the 2012 Macbook Pros without hesitation.
