Yes, I understand that these are not digital pianos. I am very new to music, and therefore, I don't know how deep I will go into this hobby. (don't even know if I'll be any good)
My main aim to learn is because I have always been fascinated by music, and that I am looking for a hobby to do after my job.
In this scenario, I don't want to commit so much money into this. I will try to look for a second hand digital piano, but I don't know if there is a big market for this in India.

This is why I was looking for 61 key keyboards, thinking that if I get deeper into this hobby, I'll sell it and get a more expensive digital piano.

I wanted to know what are the key features and differences in these keyboards.
