Casio CZ/ VZ/ FZ - Pro Series

Hi for all. Well, I have a question: I go to buy my first Synth of the 
CZ séries and I need to know: side-by-side with the other synths from 
this série, it's a good choice? How is the tecnical information of the 
Casio CZ-230S ? In front of the other CZ stuff, it have many 
recourses? The sounds are very flexible? In resume: What this synth 
can do??

It's a weird message, but is serious!
Thanks for any answer.

Michael.
