I like Speedplays, but you shouldn't go wrong with any of the others you mentioned. I think you mean "Ultegra" instead of Integra (Acura?).
If money were an issue, go with either the Ultegra or Chorus. There shouldn't be much difference between them and the higher versions besides weight and materials, I believe.
