I have spent sometime on learning from websites such as Bluebook of Piano. I often encounter the message like “buy the best piano you can afford”…Also I heard that because the mechanical difference between the keyboard and piano, playing the keyboard actually can do bad to the hands of piano playing in a long run.
I have to admit, if it is for myself, I can easily put off such expensive purchase. But since it is for son, I kind of feeling guilty if I could afford it but didn’t buy.
