If it happens to be the same board I got to play on a few years back in Utah... I would say it is a good deal better than yamaha... and I am a yamaha fan... I still play the SY 99 and actually thought about trading in mine, but decided against it as I didn't think I could ever find another one like mine.... If I could have came up with 5000$, I would have bought that Tech keyboard in a heartbeat... the Organs on it I have rarely seen matched.
