I don't have this set, but I do have two of the MTH SD70ACE starter sets, one from 2011 catalog (PS2) and one from 2012 catalog (PS3). I don't think you can go wrong with MTH starter sets. PS3 is PS3 no matter what engine it's in and they have been making these sets (and engines) a long time. I think they just switch the set contents around every few years, just as the SD70 sets they had for a few years have now been replaced by the current ES44AC sets.
I think my LHS may still have an MTH F3 set or two. MTH shows several dealers with them still in stock. My only concern would be the warranty on a 2-3 year old set, even though it is a new set. MTH can't warranty these things forever, but I don't know what the time limit is for new old stock like this? I would ask your dealer about this. Other than that you should be fine.
