Wrong. I have, and of course know full well that the RD700SX includes an impressive hammer action keyboard feel, but considering the fact that Liram, for whatever reason, opted to purchase a synth action ARRANGER keyboard, not a digital piano, of which the considerably more costly RD700SX is, think he needs to first spend time to at least EXPLORE what the PSR3000 sounds & arranger featurs have to offer, and perhaps (as SqueakD also suggested) just add a 88 KB controller instead.
