I own the SX900 and also owned the S975 and the S950. I do not believe the SX900 is near as good as those two other keyboards were. Just my opinion - but it really depends on how modern our current music has become. For me the SX900 lost a lot of the styles suitable for the Golden Oldies so to speak. I often use styles from the Tyros3 and Tyros4 keyboards. That said, I also have found some really good styles from the Genos collection that play well on the SD900.
