Recently I started playing piano. My budget is up to 20.000 usd. I basically narrowed my search up to 3 brands. I want to by a good second hand piano, not longer than 180 cm ( my room will not let me fit a larger one, the budget as well)
Which one would you select ?

this one is steinway - pretty young 1959
steinway grand piano
this one is bluthner
this one is bosendorfer - longer but pretty old 1897
bosendorfer for sale
this one is a pretty nice Yamaha
