Hello everybody. Here in Spain I'm about to buy a second hand piano but I don't know neither of two piano brand that I'm seeing. One is Hausmann. I search about this brand but all that I find is some announces of selling them. The other is Otto-Back. I'm foreigner from Asia and I don't know anything about european piano brand. I would really appreciate if anyone can comment about these two brands and which is worth to buy. (Either have 5-10 years) Thank you
