I just got my Batman 66 machine. Why can't I find any mods for this machine(only side art & plastic protectors)? Not even the topper I keep seeing online. Worse yet, there is no parts/mods on Stern's website for Batman 66 yet Stern has several parts & a $400 topper for the Aerosmith machine. A machine that The premium & LE version of the machine won't be available for 2 months. What am I missing?
