Lost Josh Hamilton. Which of these do I pick up?

12-team, 5x5 mixed league.

None of these will "replace" Hamilton, but who would you recommend picking up: Derrek Lee, Seth Smith, Travis Hafner, Lance Berkman, Jonny Gomes or Josh Willingham? Someone else I am overlooking who should be available on the waiver wire?

I guess the name of the hour (Sam Fuld) is also available, but I already have 4 or 5 guys in my starting lineup who you can pencil in for 15 homers or less, so I figure I am going to need any power source I can find.

Berkman has looked very good the past couple of days. I would try to ride his hot streak for a while.

Lee is off to a slow start, but I still prefer him to the other options available at this point.
