I would go for the Star Trek Premium. It is coming to the end of its production run so now is the perfect time to get one NIB. The light show on that game is amazing! Every light on the playfield is a color changing led. Simply gorgeous. The flow and sounds are also terrific. Definitely one of Stern's and Steve Richie's best. There will be plenty of time to get a GB Premium down the line, which is also a terrific game.
