Bachus,
You don't have to get paid to tell others in something you believe in and own.
I own two Ketron SD7s and it is without any reservations THE BEST KEYBOARD I HAVE EVER OWNED! To put this in perspective, I started with the PSR3000, then Tyros 3, then Tyros 4, Also Roland E50 and E80, also korg PA1x Pa2X-Pro, and the PA4X. I have gigged with all of them. Without a doubt the SD7 far surpasses these keyboards in what I need for my gigs and what my audiences are telling me is the best sound they have heard from me.

So, like the other poster, I too will recommend to others to take a serious look at the SD7. I can't speak for the SD9-Pro because i don't own one.

Anyway, that is my 2 cents worth.
