Not that anybody likes EXO , but I will try and help him out. If I were in EXO's position, I would have been hesitant to post pics of the Thunder Hammer to all of Macrossworld, knowing that I had no means of making such a "holy grail" item available to everyone. Now, I'm sure his close friends (who live close enough to physically harm him), could probably pressure the builder to do a limited run, but I'm afraid the vast majority of us will have to wait on a means to produce these in quantities.
I imagine quoting a price for one of these is difficult, because, as I recall, the builder did not want to/have time to make more of these, meaning this person will have to be offered enough not to be able to resist. Also, I bet this thing costs a fortune, putting it out of reach for many. For those who have commissioned customs, how much does getting a repainted VF-1 cost?
Anyway, I am glad EXO decided to show us the picture of this thing. Now, I'll wait and hope to have one, someday.
