A few weeks ago, I found an authentic André Borel 44 buttons accordina from the 1960s in a sort of second-hand flea market shop for 35 euro only. In very good condition, sounds beautiful after it warms up a little in the hands, after 1 hour of playing the sound gets a little bit better when the instrument is warmed up.

In France you might get Lucky in finding an accordina.
