As for the memorial box, look at this: https://cgi.ebay.com/Bandai-Godzill...in_0?hash=item3ef8a8f6a6&_trksid=p3286.c0.m14
Ironically, I probably should have bought the set at that sort of price, in the end I think I spent as much for the individual figures over time, but when I was just getting one here and there, it didn't seem like much compared to $400 up front. Mostly because most people didn't split it up, I was so lucky to find an auction for just the 1985 figure, I would have spent $400 on that alone, few good pieces based on that suit.
I really wish Sideshow would acquire the license and make statues, it'd be awesome.
