I bought a 120 year old Bechstein on the cheap a few years ago. It’s not in the best shape and the key action is a little bit fucked on some keys. It also has a wooden frame which means it’s liable to go out of tune faster than a more modern variant.

But despite all this, it’s far better than any digital piano because it still fills the room with beautiful sound. And the playing the with slight inconsistencies of the action is part of learning the particular instrument. Though I’m sure this would be annoying to a concert pianist who has to learn the idiosyncrasies on demand, but nonetheless the action feels more delicate and responsive than any electric piano I’ve played. Also ivory keys are superior to plastic in their cold hard tactility.

Fully worth it if you like to play and you have the space. The price of a relatively new and workable condition grand piano is similar to a very good digital one.

Very old ones tend to be cheaper:
