Has anyone had experience with the Donner digital pianos? I've been considering purchasing one as a beginner and I've seen various models that seem affordable, but I'm curious about their quality and durability. Specifically, I'm looking at the Donner DEP-20 model due to its features like weighted keys and multiple voices. How does it compare to other entry-level digital pianos from brands like Yamaha or Casio? Any insights on sound quality, feel of the keys, and overall performance would be really helpful!
