My recommendation is to buy them.  You can probably find them in a local
cd shop for the same if not lower price, especially when you take into
consideration the handling fee.

The performances are wonderful.  Hopefuly, without offending anyone's
sensibilities, I'll say that for me some portions of Milstein's perfomances
have a very "jazzy" feel to them.  When I listen to them I feel like I'm
being sucked into an aural universe that excludes everything else; and the
longer the piece goes on, the more totally enraptured I am with the music
and music making.

happy listening,
