Here is the very best one, IMHO.
This is part 1, but it gives the feeling and structure of the piece, i.e. a theme with variations, which is often overlooked and indistinct in many piano performances.
Based on this Heifetz performance I think Michellangeli gives the truest and best piano performance I've heard. Anyone wishing to learn the piano version would do well to listen to the Heifetz performance first, which well conveys the architectural structure of the piece, each variation like a masterfully carved stone placed to create a musical cathedral.
