i have a yamaha dgx200. i bought it for midi-ing to the PC. be careful of the midi out, if you unplug or move the keyboard a lot while plugged in, you may find that the midi connection gets faulty. i had mine repaired then it broke again, so i bought a korg K61p controler keyboard which also has audio piano, organ, strings but no drums. cheap and cheerful.
hope you enjoy your new gear
