In general I think it is best to obtain a complete set of important works maybe for the simple reason of the shame to be without these works in your home. I for one couldn't imagine being without a complete set of Beethoven, Bruckner or Mahler symphonies, so I bought the Klemperer, Jochum, Kubelik sets (respectively) taking into account budget prices. I then of course "beefed" up the collection with many other performances and interpretations. David Rothstein
