I was offered the korg pa800 and yamaha s900 at the same price. I chose the yamaha because its sounds blow the korg away and its styles (including intros,fill ins,endings) make the korg feel ashamed to be called a keyboard. Only a handful of the korg styles sound decent. The korgs fill ins and intros STILL stick out like a sore thumb. Yamaha - you rule! (my 2 cents)
