So my old keyboard couldn't be repaired. Old batteries leaked in it and the acid destroyed the inside
After two weeks of thinking I purchased a cheap beginner keyboard. I hope I won't regret it. I know it's possible I won't practise. That's why I've ordered one for 89€ so it's not such a great investment... I read reviews and they say the sound is good which is all I really need. Just a simple piano sound, no fancy effects needed. Anyway, I hope I won't end up with another dust catcher.
