Hello, my name is Leo and any help that anybody can offer me would be greatly appreciate it. I'm looking for an affordable, realistic sounding electronic keyboard. I don't want nor care for any of the extra stuff such as: midi capabilities,built in hardrive, songs etc....
AS long as it has 88 touch sensitive keys, realistic (or as close to it as possible) sound, and a sustain pedal I'll be happy

Any suggestion would be very helpful, so far I have come across a couple of promising keyboards such as the yamaha p70(formerly p60) and the casio px100. I don't want to break the bank, 600 or 700 bucks tops.
Thank you in advance for any feedback
Leo
