I wouldn't spend as much money on getting a good-looking one, as in finding one that FEELS like a piano. I don't think any of them (that mere mortals can afford) will ever feel like a real piano, but some of them are far better than others. Roland used to be the standard, but I'm not sure what is now.
That being said, I've played $25,000 acoustic grands that I didn't like the feel of. And again, you're talking little ones. When they get great, buy them a nice grand if you can at all afford it. :)
