Thank for your help, dear friends. You have opened my eyes (and ears) in my doubt between PSR740 or KN5000. It likes evident that KN5000 is better buy; so, I will go for it. Same of you ask me where I can buy KN5000 at 1200$. I must tell I am in Spain and, as Technics don't make KN5000 from a year, the rest of KN5000s are at lower price.

Now I have a Roland E-36, and I would like to convert its styles (and other Roland keyboards styles) for to play it on KN. What is the best manner to do: using the converter disk of the own KN5000, or ask for those converted styles on the net? If you consider that the second option is better, do you know where can I find converted styles from Roland to KN5000 on the net?

Thank you for hour help.
