Dave, you're certainly right about the Korg. As you probably read, I just got the G800, and some of the Blues, R&B and Rock are outstanding.
Of course in today's world, all of the styles from all of the keyboards are available if you put in the work.
I can make a case for the G70 and the Tyros2, in addition to the Korg. I would have no reservations about any of these three, except for the heavy weight of the G70.
One other thing about the Korg is is that it's extremely editable and you can customize it to your heart's content. All the factory styles can be replaced with your own if you wish.
