Diki..., as far as I'm concerned I would seriously question the credibility of someone who likens a SonicCell/Fantom X sound engine to that of a cheap Casio.., and then comes to that conclucion based on a shotty video demo posted on YouTube of all places.

I've seen very poor quality S-900 demos (that due to the shotty camera) could easily be compared to a Casio as well.
