This is essentially a newer version of the model I have used for 20 months as a workhorse in the field (2013 MacBook Pro Retina). I still use it daily as a 2nd machine for some grunt work.
Very approachable price for a solid machine:
There is also the 2.8 GHz / 16GB / 1TB model at $600 off.
Or you can go whole hog with the 2015 MacBook Pro Retina 2.8 GHz / 16GB / 1TB model, but the gains are mixed, as shown in my review of the 2015 MacBook Pro Retina.
