The company its from is Casio as you'd probably know is well known for its quality keyboards. The model is CTK-800.
I brought this keyboard 2 years ago. It hasn't been used much because unfortunately I became busy with school work. It is still in fantastic condition.
There is an adapter or you can use batteries. Its about 1 metre in length.I have the manual too.
The keyboard itself has a song bank, a piano bank, tones bank, rhythm bank, it also has a beginner programme where you can learn how to play the keyboard. You can plug in a microphone so can sing along, and play at the same time. There is also a slot for USB cables, so when you record your music (which you can on the keyboard) you can transfer it onto a computer.
This is truly a fantastic keyboard; you can come over take a look at it. And if you're happy, take it home with you.
Don't hesitate to ask if you have any queries! Thanks! :)
