Donny,

Levy's (Canada) makes a heavily padded one specifically for PSR9000. Yamaha PKB 1152's padding is a bit too thin for proper keyboard protection. I am currently using a Levy's padded keyboard bag for my Yamaha S80 synth to transport PSR9000 to save money since I seldom move them together. See my old post:
