I saw it on my way into town, somebody put out a casio WK-3000 piano out on the curb for free, with the stand power cord and even manual. The craziest part is its fully functional. Not a darn thing wrong with it 'cept some dust. Now I have to learn piano.

Apparently that can be the biggest obstacle surrounding ownership–transferring one. Like pool tables, they can sometimes be priced cheaper than one may expect – primarily because the new owner is also going to be tasked with the removal of the extra-large acquisition…
This is why, when I decided to get my kids a piano, I got them a digital one. Way easier to deal with, logistically speaking. (And also has features like MIDI and the ability to use headphones instead of making the house noisy, which is nice too.)
