I did indeed buy one for myself, although I did not spring for the motor and battery pack kit, as that nearly doubles the price.
While it is a different gauge, I posed it on some gargraves rail for comparison pictures. Lego scales are a bit of a guessing game, but I would put this closer to 1:45. As far as details go, think of it as railking model. Not meant to be perfect but you certainly get the idea.
Overall the build was enjoyable although repetitive given the subject matter. My big issue with the model is the connection points are flimsy and show big gaps. There have already been several modification recommendations posted online from simple to complex. I do like it for the money.
Also, everyone should be aware the Brick model railroader is now selling kadee couplers molded right to lego compatible bricks. If gauge correction were to become widely accepted in the lego models, it would really open up a whole new world of interaction.
