Nehemiah Gordon has taken to putting a recording of the weekly haftarah on his website each week. He has a nice Israeli accent, good diction and is very expressive in his intonation. You can find his reading at his website: http://www.nehemiaswall.com/prophet-pearls.
*****Disclaimer: I neither endorse nor un-endorse the interpretive discussions of Torah and haftarah and anything other thing which appear on his website.
