Yamaha electric piano, which one is good? Those who know electrical steel come.

I majored in electric piano. I can tell you that it's a domestic brand and its reputation is getting worse and worse. The quality and so on, and the advertisement is also bragging. Yamaha is a professional musical instrument manufacturer, and its comprehensive strength ranks first in the world. Do you really think you can't use iPad, download piano-assisted practice software, or buy a Casio luminous key electronic piano to assist practice? Actually, the piano is not difficult. After playing for so many years, I still practice more.
