Leon Panetta, former House Budget Committee chairman, former OMB director, former White House chief of staff, and former California congressman has been nominated by President-elect Obama to be the next director of the CIA.
I've known Leon for more than two decades. If you're looking for someone from outside the agency who is an honest broker, a great inside player, and as good at dealing with Congress as there is, Leon absolutely is the right person for the job.
But Leon will add one more thing to the Obama administration: yet another very strong budget expert inside the cabinet room. While his primary responsibility will obviously be the CIA, we shouldn't discount the additional expertise he'll bring when he sets up shop again in D.C., or in this case Langley, VA.

Jamie Gorelick redux?
Panetta may also be good for reinforcing the wall between the FBI and CIA so that shady campaign donation sources are difficult to investigate.
