I dig it too. I'll get one for sure.
There's a lot of other VFs out there, but it seems like Hasegawa is sticking to stuff that's shown up in the shows/movies.
The only one that really baffles me is the lack of VF-171 since there's multiple versions and it's in multiple shows (I think). Seems like it would be worth doing.
I can't really see Hasegawa doing obscure video game and artbook stuff.
That said, I really wish they'd get around to the following:
Tornado Messiah (at least it showed up in a movie)
Armored VF-25
YF-29 Durandal (at least it showed up in a movie, also)
YF-30 Chronos
Armored VF-31 (actually I wish Bandai would do this too)
VF-2SS Valkyrie II (at least it was in a show)
