I have purchased my first digital piano recently. The Roland FP-4 is an excellent keyboard. Full set of 88 weighted keys, in a compact body, that Apple iPod white color, and built in speakers is exactly what I wanted.
In particular, the weighted feel (or the action) is quite nice on the Roland and more of what I wanted, even though it is in a higher price range than a number of other keyboards.
One thing I have to say is that any of the advanced features on the piano do not have an intuitive interface to use them (recording and playback, etc).
The music rest is neat on the white Roland as well. It is a clear fibreglass back with white metal base for the music to sit on.
