Dreamer was very pleased with his PX-5S, and Casio have made some awesome pro quality synths in their past with the CZ series.

If they put as much effort into an arranger keyboard as they have done recently with synths and digital pianos, they'd quite likely come up with a real game-changer and have Roland, Korg and Yamaha scrambling to keep up.

So far, in my opinion, Casio's arrangers are still a bit short of the mark, but who knows what the future will bring?
