Pashmee,

I use Korg PA80 which costs about $2000 + tax. There are things I like and don't like about the keyboard.

* I like its sounds a lot.
* I also like the fact that you can replace all factory styles with user styles.
* I like the voice editing capabilities
* I do not like most of the factory fill-ins and hate the break, but there are people who like that.
* I do not like the fact that sometimes the voice truncates when you switch to another voice.
* I don't like that it has only two fills, but still I can program intro1 and intro2 as fills and end1 and end2 as intro and end and that works fine for me.
* Since I use both fills and intros as fills in the user styles, I have two sets of fills that behave differently; I like that too.
* OS may not be as user friendly as that on Yamaha's, but you can learn it. The only problem is when you have to press more buttons than necessary while playing live; your time is limited no matter how well you know the OS.
* More than anything else I dislike that Korg support (USA) ignored my emails several times (not every time).

By count, there are more things I dislike than I like about the PA80, but the things I like still overweighs the things I dislike.

Hope this helps in making a decision
