Hmmm. I never realy heard of the casio that you are talkin about.

But I got a DJX. It has many.. And I mean many of that tehcno/dance/house music stuff on there almost to much.

I have owned a casio keyboard befor. and the diffrence between the two is that yamaha always seems to be ahead of casio by a step.

Does Casio have realtime recording [ ???? ] I know Yamaha has great recording effects.

Casio is more of house Keyboard ya know. If I were you I would go with the DJX, but it is your desicion.

I remember right befor I got my DJX I got a Casio [ becuase I could not find the DJX anywere ] And I was kicking myself in the *ss later becuase it was ... well it .. . It was just sad man. The DJX is made for making music all by yourself [ no drum machine, no this no that no bla bla bla expanion, just you your fingers, your mind and the DJX, and probably some samples ]

Welp thers my two cents.
