Those two cds seem to be hard to come by.
Not hard, just not cheap. When I ordered them on Amazon they shipped from Poland. Still available for $25 + $4 shipping, but they are worth pursuing in my opinion. I enjoy them very much. Relatively expensive for CDs, but not in general. You could easily pay $60 for dinner plus wine for two at a decent (not expensive) restaurant. And by the next day you are hungry again! But these CDs can satisfy your musical hunger for many years. ;^)
