Literally the only thing I do not like about MTH PS2 or PS3 upgrades is that annoying gooseneck harness. I suppose one could take extra time and put a better one in. Other than that, PS3 is fast becoming obvious that it is better even than Lionel's Legacy. Lionel's Legacy edge is the actual sound but all the perks provided by PS3 is unbeatable. I have locomotives that are upgraded to Lionel Legacy, a few 3rd Rail upgraded to ERR (Lionel) and a few K-Line upgraded from TMCC to PS3. So what I'm getting at is almost every one of my upgraded locomotives is Lionel or Lionel controlled stuff. I do have one (ein, uno) MTH model which I got upgraded from PS1 to PS3. To me this reflects that the DCS system is in reality superior to TMCC, ERR, and even Legacy. (Note how many versions of TMCC there is here - Three!!! compared to MTH's DCS system (which still uses the same remote!!)
