On its own, I would recommend the book. However, future developments could make the purchase less useful. All of the modules were built using GURPS Vehicles, and that book is going to be completely redone for 4e. Also, they are completely changing the modular system with the introduction of Interstellar Wars. As a result, I have no idea of how useful it will be as things go forward in GT. (Or, possibly, if GT itself even goes forward.)
