Yamaha call their electric pianos "Clavinova" The have a full range 7.5 octave full size keyboard and the keys are weighted to simulate the feel of piano keys. Not being a pianist, I do not know exactly how they feel, though I have known know people who have them. I have also heard them played - they sound pretty good.

Google "Yamaha Clavinova" for more info and you will get plenty of relevant hits. I am UK based, so Google brings up UK based sites for me. So it is better if you Google yourself rather than I post links.
