Paul,
I sell a custom made bag from Levys Case Co. in Canada. It is made to fit the PSR9000. It has heavy beige colored pading inside and includes a special compartment in the inside cover for the music rack. It has large pockets and on each end it has a velcro flapped covered pocket for things like AC adapters and sustain pedals. It sells for approx. $129.00.
