You've got to be joking, right technicsplayer? I think when you searched for the Musikmesse URL link you evidently got the one that was held 2 or 3 years ago. PS: I personally owned the Casio WK 1800 and I can tell you straight up that it doesn't hold a candle to my Yamaha PSR 2000.

Ha Ha Ha LOL lol Hee Hee Heee Ha Haaaa Whew!! That's rich. Maybe someday Casio will get with it and start producing some world class Arrangers but at the moment there basically the bottom rung of the totem pole in that arena and I would imagine most other arenas. The MZ 2000 was there best attempt so far but it is way inferior than todays top Arrangers. But if you are on a tight budget and a beginner then I think the WK 1800/1600 would be a good starter Keyboard.

PS: Please don't take my laughing out loud outburst personally. I am not laughing at you but at the blatant mis-information you stated and I'm thinking your either not aware the information is outdated and not in correlation with what is currently known and true in regards to Arrranger Keyboards or you maybe work for Casio or your just joking around.

Best regards,
