It would be easier to help you if you were more specific about exactly what you are trying to do and what it is about ContourPlot you find lacking.

One possibility is using ImplicitPlot. Consider one of the examples for Plot3D in the help brower, i.e.,

Plot[Sin[x y], {x,0,4},{y,0,4}, Mesh->False, PlotPoints->40];

Then a slice at z = .5 could be plotted using ImplicitPlot as

<<Graphics`
ImplicitPlot[Sin[x y] == .5,{x,0,4},{y,0,4}];
