PSR S Series S700 to S790 and S900 to S990

[chirath]

hello everyone
I'm planing to go for a S series one of above and trying to figure out the best keyboard for me with my budget. I know im getting a used one but want to compare the advantages of each model. I heard mp3 option has been introduced after the 910   model. and what are the other new things?
If there any compression chart then it would be nice.how ever appreciate your advice
advice
Thank you

when buying a s900 these models have issue with lcd screen going bad.i had owned one and at that time Yamaha paid for the replacement cost not sure if the s910 had the same issue

The 910 does not have the screen problem that the 900 does.  The 910 can play both the older SFF1 styles and newer SFF2 styles.  The 910 Music Finder can call up styles stored on a USB drive, a very useful feature for anyone who uses the Music Finder.  I am very happy with my 910.  The downside is that any units you might find for sale are already about 10 years old.

This was not a problem with the S-series keyboards - only the standard PSR-900, which was replaced at no charge by Yamaha.
