In my opinion, you'd better use the Medley electronic organ. Although it is a Casio Japanese brand, the relatively low-end model CT-788 is actually similar to that made in China. . . . . The most important point is that Casio's single finger and metaphysics are a system. At present, the teaching books on the market are all based on Yamaha's single finger and metaphysics! . . . . . . . Actually, why didn't LZ choose Yamaha? . . KB280 KB280 is much better than the above two pianos in timbre, rhythm, feel and sound quality! The price is around 2 100!
