Guess I'll have to add my 2 cents worth.  I'm _not_ an expert, but
I do own both a 1928 player and a 1970s Duo-Art.  If space is an issue,
the smaller piano is nice.  I enjoy the one I have.

However, if I could have only _one_ and I had to choose, I'd keep the
1928 piano.  You can't beat the sound, cabinetry, or touch if you play
it manually.  I'd look for an older piano, too.  They really are what
you expect a player to be.  If you buy a 1920s vintage player you won't
regret it.
