Still alive in Japan! Picked this up today from the big department store, Yodobashi Camera, in Akihabara. Decided to get this (and probably RG RX-78-2) because I'm fairly sure I can fit them in my carry-on when I fly home next week. That was my main concern, just not having enough space in my luggage to bring stuff back, but hopefully those two boxes are thin enough. The price was really good too, 1610 yen, almost 30% off. No shipping fee either!
Hopefully I'll get some other things tomorrow as well (they were sold out of the RG RX-78-2 today).
