The current model is the Electone Stagea, only sold in Asia.
This is a marvelous instrument; listen to this performance by Qi Zhang (her transcription from the "Love of Three Oranges") and be awed:http://www.youtube.com/watch?v=iKorq7dE4gM
After seeing this, I inquired at Yamaha Canada why they don't sell these in North America. They said there was no market for it (with over 300 million population?). I told them they're wrong, as I would buy one in a heartbeat.
Another issue is the (apparently) different voltage of these organs compared to the North American one. They told me that plugging a Stagea in the electrical system of my house can make it burn down. I'm not convinced this is true, as I've ordered several appliances made for Japan use and the voltage is the same as in Canada.
Some people have imported such organs in Europe/North America, but then it's extremely costly and good luck if you ever need service on it.
