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.
Plus it’s only a 76 key board vs the 88 keys on a real piano. So some songs are literally impossible to play on many electric pianos.
On the other hand, electrics don’t take up as much room or weight as much. Which makes them far easier to move and a lot easier to get help to carry down the stairs.
