I got one.
So much assembly required and so little time, I have not even taken it out of the box. I was hoping for a little more snap together assembly from Micro-trains. You've got to glue a bunch of stuff.
I don't exactly regret the purchase but Mark's shapeways stuff is not going to be more difficult to assemble. At some point I will probably kitbash a full train together with parts from both sources.
The blade hubs from MT are a nice part. The nacelle and blades are a little ho hum.
