I have yet watch Gurren Lagann, but those mecha are growing on me. UN Spacy's pic shows lovely details, hope it is diecast.
By the way, for those whom own Fewture Getter 1 & 2, do you find the Getter 2 has better fit than the Getter 1? A few things (e.g. the cape, the chest plate, the belly plate) tend to fall off from my Getter 1 if I don't handle it carefully. Where as with Getter 2, everthing seems to fit better and has better posability.
