I'm from the other forum. I have a KN6500 for sale at a very reasonable price. This is not the reason for this post. I have an opinion----

I would never think of buying a computer that has less features. I do not want to buy a computer or keyboard that I will outgrow quickly. Most of the new high end keyboards can be played in a simple manner, Staying at a beginners level.
When you become ready, the next level is there waiting. I would buy the best I can afford.

Most intetested people with interest purchase a beginners model in the $150-300 range. Shortly after they have lost their interest. It is terrible to play a set of drums that leave much to be desired. Or to play a trumpet that leaves you nowhere.

Success=A good student,a good teacher, and a good instrument.

I can say that the Technics is the friendliest keyboard for beginners or advanced players. This statement has nothing to do with my keyboard.

This is my humble opinion. It comes from a good bit of knowledge of Technics keyboards, and very little of others.
