No, Rich you're comparing Apples and Oranges...
A Lander (did you add it's cost into your Mars Express costs) and a non-polar Orbiter isn't the same as two Rovers.
Look at orbiter cost and lander cost on other similar missions and see what I mean.
Beside why is the costs your most important indicator of worth. I would say science and cost combined are a better indicator. And what comes out of the mission is far more important than what it cost. Right now should we valve Mars Climate Orbiter as much as Mars Express?
You yourself being annoying doesn't mean you have touched on some sort of conspiracy thing...
