Jose,
I love the PA2XPRO...If I were you...I would NOT judge the PA2 by what you have heard on the demos. You should go somewhere to play one yourself and spend at least 1/2 day. It would be best to go where they have a person that knows the keyboard well.

This thing sounds awesome!
And the user interface/programming/MIDI implementation is superb.

In the end it is up to you to determinw if you like the PA sounds styles functions etc.

Have you been to the Korg PA forum site? http://www.korgforums.com/forum/phpBB2/viewforum.php?f=50
