After watching a lot of demos, I think the wise choice pour somebody who wants the best of both worlds actually is
Korg pa900 + yamaha psr-s950
Even buying these two keyboards , it costs you less than a Tyros.

It is the choice that the person on the video has made without doubt.
We could see a PA900 on top and the S950 at the bottom on the keyboard stand.
The music is really inspiring but very oriental too.
Very good and strange sounds played on the Pa900

I made a post on my web site : KORG PA900 NEW ORIENTAL SOLO
