I know a lot of folks think a traditional piano takes up too much space now. That may be totally so for some.
Supposedly though, if you have it in a proper place and not exposed to high humidity and the such, they really shouldn't need to be tuned twice a year like the industry suggests. The man who moved mine two times is a professional tuner and each time, he played on it a little and said unless I was going to play in a band with other instruments, mine didn't need re-tuning after the move. Of course if I insist on paying him to come do it, he will come and go through the motions and it may or may not sound recognizably better.
I think there is value in any style of keyboard, depending on what you want to use it for, but to me, if you play a lot personally, I don't know how you would not desire a full sized, traditional piano.
That's easy for me to say. I have one and I don't play it much at the moment. LOL.... but I was fortunate that my tv fit nicely on top so that they could occupy the same space. If I didn't have the piano there, I would need to have some sort of table there for the TV. Since they can share the same space, I have room !
My younger sister and I are the only two of we 5 siblings that took lessons. My older sister never took up a musical instrument, but loves music. Both my brothers were drummers.
Obviously also, mine has sentimental value to me. :)
