There is an old saying: "Condition is everything"
The 700EWX in the auction link was "partially restored", and had a chipped wheel. In addition, there are some folks who do not believe the "X" variation was done at the factory.
If you are using the 700EW (no X) I linked as the "10,000 dollar engine", then one has to consider: the display board was included, individual and master boxes were included, and finally, the engine and tender were in excellent shape.
