Personally the Toyworld version makes a much better shuttle mode. I also prefer the look of the train mode.

If I was buying Independent Masterpieces I'd most likely grab this. I love the Juxtaposition of the shuttle wings on the robot back against the steam train wheels on the inside of the leg.

it's odd, Astrotrain used to be a mix of the super advanced and the practically obsolete. now he's just obsolete and obsolete.
