I am looking at buying a Nord Stage 3 (88 key) both for at home (although I also have a grand piano) and performance. I am wondering how realistic they are to play as I have only played the stage 2 but that was a long time ago and I can't really remember. I love the piano sound but does it feel like a piano? I would prefer a Nord to a Roland as I also prefer the synth and organ on Nords so please don't suggest I get a Roland.
