Depends on how much you want to spend but you can't go wrong with an 01W/Pro at the right price. It is older and will not have all of the features offered on new synths though. Alot of us like the sound of the older models over the newer ones but that is subjective. I would recommend getting an X5DR and a master keyboard like Fatar. The X5DR is discontinued and is being closed out at under $400 ($850 retail).Does she want a full 88 key hammeraction or synth action??? Big difference in price.
