text: It's a matter of personal preference. (and of course nothing beats a real piano.) But Digital pianos are easier to maintain. I suggest going to the store and playing all these models. I personally like Yamaha. I'd stay away from Casio. Don't know much about Kawai. Kurzweill and Korg have some of the leading technologies as far as sounding like a piano is concerned. You'll want something truly weighted to feel like a grand piano.
