Or plan the trajectory so that the gravity it does encounter actually helps rather than hurts (gravity assist). The probes would be nowhere near where they are today if they didn't swing around Jupiter and/or Saturn (can't remember) and steal a bit of energy to slingshot themselves even faster.

The Ion drives are very cool, they require no propellants only solar panels (or a nuclear reactor or something).. but the amount of thrust they put out is so small it requires a loooong time to accelerate (think piece of paper sitting on your hand amount of thrust). Great for getting around the solar system though, as long as you have time on your side.
