Hi, the OP was: "But what I really want is not to have to do this, and rely on the semi-intelligent mechanism of Mathematica to pick an appropriate number of contours and their values, THEN use those to draw the legend." and using the Tooltip[] in hte contour plot is a way to get the levels from the final plot.
