I'm putting him into my "Transformers that are significant to me" part of the collection. Kultur: because he's my avatar on this website and I love him so much. Universe Hound and Ravage: because they're the first 2 Trasformers of my collection Prime Breakdown: my favorite character from Prime and I thought I'd never get his figure because he was (and is) going for so much, but my Aunt and Uncle got him. (I still don't know how much they paid for him) Titans Return Kup: because his name is the name for my profie here on TFW2005. Legends Astrotrain: because he's my favorite Transformer of all time.
Everyone should have a shelf of all the figures that are significant to them. It's nice to look over at 1 shelf and just see all of the Transformers that have some kind of significance to you.
Character. As for which Astrotrain you should get, if you have some extra cash to spend and like the G1 cartoon look, go for Takara. If you're on a budget and want the G1 toy look, go Hasbro. But I say go Takara anyways since it has a better feel to it than the Hasbro version.
