That's a pretty good price for that machine! It's almost top of the line. The only other thing that wasn't maxed out was the SSD. I had the same one but with a 750GB SSD. I sold mine last month for $1300.
Mine was pretty reliable. I got the display replaced because it had image retention/ghosting issues. After that, it was fine.
Apparently, some machines may have video card issues. However, if that happens, it is covered until the end of 2016.
