I have been playing keyboards (mainly arrangers) for past 5 years and was looking for a new board recently for an upgrade. Am confused between PA700 and SX900 as both of them were quite equally priced in my country. And moreover I was also interested in the MODX synth though its a complete synthesizer (curious in trying new stuffs). But now I can't take the decision of which one to buy of these three. And I don't have any store in my region where I can try these out by myself. So I need help.
