The main problem with 65-note push-up players, in my opinion, is the
relative difficulty of finding rolls.  Also, enjoyable or interesting
rolls are not common.  The last push-up I saw in an antique shop about
five years ago was unrestored, complete and was for sale at $200.

I guess the point of restoring a push-up is to show the rareness and
unusual mechanical design.  Definitely a museum piece.
