Hello guys! I own Casio CZ-101, in full activity. I love their 80's vintage sounds, which use in ambient music and chill out. Usually use it with a Boss DD-20 delay to record (do not use MIDI in this case).
Also I have a CTK-6200 where I teach to my son. Is a good keyboard.
I've had a CZ-5000, at that time also had a Yamaha DX-100 which was part of the setup along with a Korg Poly-800 II. Good times!
