Yesterday, I gave $80 for this beautiful K-Line FM Trainmaster - has TMCC, RS4, fan driven smoke, electro couplers, etc., and they all work just fine. My first functioning TMCC loco, I had a ball learning how to control it. Didn't take long to pop the command base antenna wire loose (alligator clipped) and have a runaway!
This is one of the engines of my boyhood dreams, although when I was 9 years old, it was Lionel's version that had my eye!
