Where should I look for the best fare from Los Angeles to BA, leaving mid-May returning mid-July?

Delta has LAX-EZE for $791 - is there much chance of finding it cheaper than that?

If there's a different forum where I should be posting this, let me know (and sorry).

thanks,

Seems like a very good fare to me. Rock bottom specials MIA-EZE are usually around $550, so considering you are coming from LAX it seems like a good fare IMO.
