Look at your own preferences. The design and positioning of each brand are different. I have worked in a musical instrument store and have seen many brands of pianos. Generally speaking, the brand of single piano or full piano is much better.

A good brand of single piano:

Yamaha Guitar: This is an old brand. Generally speaking, it is recommended to choose this entry. The workmanship is good, but the shortcomings are obvious. The bass of most models is very loose.

Dove Guitar: The price is moderate, which is suitable for playing with fingers. The disadvantage is that the board is relatively thin.

EZWAY guitar: It's very affordable, with acceptable fingering and singing skills, simple and classic model, and acceptable timbre and feel. Generally speaking, my students are recommended here, but the disadvantage is that only official website has an appointment and is often out of stock.

A brand with a good list:

Taylor Guitar: Very suitable for playing and singing. It is usually equipped with an electric box. The main advantage of this brand is on the electric box.

Martin Guitar: It's more expensive, all kinds of songs can be easily controlled, and the models are classic.
