There are two other products,covering zentraedi ships and more human ships, but sadly, when i checked, they were both sold out. So if someone kindly wants to post them...
For the uninitiated, there's a Japanese company called Skywave/Pit-Road who make 1/700 model warship kits, whose product announcements look a lot like the back cover of this book. :)
Also, I definitely second the request for the other two books in this series. I'm working on translating this one, slow going but I have a few pages done.
