I kinda liked Escape from Kalisz myself. it set the tone for the game.
Check out this variant of Escape from Kalisz that I posted a while back.

You might also want to consider Kings Ransom which is set in Iran. I liked it because it wasn't as open as the other modules, the players had a mission which could lead to bigger and better things. Plus gas and air support is available in Iran...
