Good morning, my name is Claudio Sarleti and I live in Lumezzane BS.
It is always pleasant and instructive to read about your personal experiences.
I am not very familiar with forum rules and I apologize if I make any mistakes.
I am studying on a digital piano but now I would like to move to an acoustic one; I have a low budget, 2000 euros max, do you have any advice to help me avoid making a mistake in my purchase?
Welcome Claudio. With two thousand euros, you will evidently have to turn to the used market. If you manage to find a Yamaha or a Kawai, you are lucky. Otherwise, the only possibility for evaluation lies in testing the instrument: you should have the opportunity to try it before choosing.
To be sure, you must try all the keys and first try to understand if there is homogeneity of sound and touch response. Secondly, evaluate whether the keyboard feels like it has an appropriate weight for your expectations and whether the overall sound satisfies you.
You will surely find some shops in Brescia that sell used instruments.
