Polystyrene records are only good for about 20-30 plays no
matter what shape stylus you use.  I'm not sure what you
mean by "worldwide standard" but most "LP" styli are truncated
eliptical nowadays; few conical are made. Styrene is harder
but also more brittle than vinyl and so the high frequencies
will literally break off in the grooves.  Columbia was the
chief proponent of polystyrene so I'd imagine that of such
records available today, new or used, they'd be on the labels
now owned by Sony.  Radio stations loved the Columbia records
because for the first dozen or so plays they are noticably
quieter than vinyl.  They could dupe them to carts and then
play the carts to death rather than the records.  But for
repeated play, like in a jukebox, polystyrene records are
terrible.
