If you want something for a cheaper price, then buy either a good name late model used name brand cabinet piano or a new lower priced name brand digital piano. Those instruments sound and play much better than the off name or house brand 88-key digital pianos. Simply put, stay away from the brands I mentioned in the title of this blog if you want a satisfying piano playing experience, unless you have low expectations. It's unfortunate because there are parents out there who know little or nothing about pianos and how they need to play, and then they purchase these lesser known lower price "attractive" digital piano brands for their kids thinking they have done a good thing. But in the long run they have not really saved money and potentially made it difficult for their kids to learn to play properly once the child starts taking lessons and needs to play correctly.
