Casio SA 77

This keyboard was bought for my youngest daughter. I find suitable keyboard a long time, but only Casio SA 77 is okay for small kids.
Very simple for operating, switch modes etc. Kids can operate with this keyboard by themselves.
100 quality sample banks, a lot of pianos and other great instruments for this price. Very nice sound also included!
I think I can add only one lack - AC adapter not included. Suitable power supply from the guitar pedal for example (9V).
Batteries spend economically.
Resume: great piano for kids, interested functions for study and simple performance.
