I'm going to throw in Maria Bartiromo. I know, the mainstream accepts her, yet I'm fascinated by how "off" she is. The shape of her face is unusual, she's heavily made-up, and her voice isn't what I would choose -- I suppose that's why I go along with Lorraine Bracco, because her Bronx acccent in Medicine Man grated but in an intriguing way -- and yet somehow it all comes together and works for her, making her a sex symbol for financial geeks, something I'm not sure Consuelo Mack has ever quite nailed.
Oh, and try this one: Lesley Stahl.
