My must haves for all my new Sterns.
Shaker motor
Pinnovators headphone jack and sub output combo
Speaker panel light kit with a cool insert.
Maybe a color DMD for the right title. This one will take quite awhile to get colorized though.
And for this one I got the colored balls to replace the captive balls.
That's about it.
Maybe the little mirror that shows the PKE inserts better as that is useful.
