I've used an old Yamaha PF100 (portable version of the Clavinova) for years as an alternative to my acoustic. I think Yamaha has the best technology (properly weighted keys, great grand piano samples, and the best internal speakers of all the competitors). I think you should consider getting one of their newer 88-key portables - they come with a solid spinit type base stand for home use but offer the flexibility of being able to take it with you (to events, family reunions, etc.) or to just tuck it away in a closet when you don't need it. Check out the new models at Yamaha.com. They now come with an amazing number of bells and whistles as well as education software that can aid in teaching your child. Good luck.
