I have a great case that I used for the Yamaha PSR-S910...custom made by a guy, Terry, in Halifax, Nova Scotia that has his own business called,
"Sewman". http://www.nslocal.ca/results.php?hide_id=1882&hide_stylesheet=3 Excellent work and very reasonable prices.
I'll keep it for the next S-series.
Ian
