I think you are right Leeboy. It is all personal and of what kind of music you play. Yamaha sound to sweet for the kind of music I like. I like soul, disco, funk, dance and modern music from Shakira, Lady Gaga etc and the Korg PA's are IMO better in that while Yamaha is better for ballroom music. The Tyros 4 is a great instrument and sound to me better then the Tyros 3 but not for the music I like.
