Dear chakster, ''free will'' and ''free choice'' are inscrutable notions.
The first is invented by Kant the second is suggested by liberal
capitalism. I think that you assume both in your advices (grin).
Even the manufacturer have no ''free choice'' for cart parts but
are dependant from their supplier. There is no sense in ''longing
for , say, Berillium cantilever'' if those are not produced. You are
what German call ''idealist'' which is curious attitude in ''not
ideal reality''. But it is true that we can afford idealistic attitude
in our forum and be pragmatic in reality. To me this means that
if you own some very good cart but, alas, with wear out stylus,
the pragmatic solution is to retip stylus only. If cantilever is also
damaged then, obviously, the combo of both can be got for about
$400. With present cart prices not an difficult decision.
