Why pay $350 Dollars, just download the instructions on buy the pieces off Bricklink. This is was I did when I wanted to create the Blacktron II in the Futuron colour scheme. Also I tend to like both sets of base plates, I bought the black ones myself and they were of great use but there more for creating the idea of a city or space station, something more completely man made. The gray ones give a better look of the roads being laid over bare rock especially when you introduce the plates with the craters. I would love to see a 48*48 baseplate with roads through them which would allow more building space on the side and maybe some craters. Also 48*48 baseplates with craters but a few different kinds to create more or a realistic look and less of a repeating pattern. And with all those rocks you have to put everything up on supports, much better looking bases then.
