Honestly, the only one I found to be what I would consider highly attractive is Colombia. Turkey looked like one of my Italian teachers in a picture somewhere, and so she scores up there, too.
Beyond them, I personally didn't find many of the other contestents overly physically appealing.
Edit: Well, maybe a handful of others could be classified as cute. Perhaps russia, puerto rico, and two or three others.
Edit again: And now the girl I'm talking to is convinced they're foine, and is having fun sending me links and making me say yes or no.
