Hi George: Wow, I too had the chance (over the months) to audition most all the keyboards you mentioned in your review, and came up with just about exactly the SAME ratings & conclusions as you did. I also agree with you that all of the boards mentioned are fully capable of creating terrific sounding pro level music. The rest is up to your musicianship, and no keyboard can make up for any deficiencies in that area. Purchase the keyboard which you like the sound & styles best, and the rest is up to you and the time you spend developing your chops. - Scott
