GUI I believe this is one of the better ways to accomplish your task. A single timing belt running to both lead screws and the drive motor. More or less the belt would form a triangle with the lead screws at two corners and the motor at the third.
A second alternative, if space allows, is the drive motor with a sprocket, midway between the two screws, driving sprockets attached to the screws. (visualize three ring circus)
