quadric surfaces

Hello all...  I'm working on some Mathematica for a Calc IV course and
needed some help with quadric surfaces.  How can you get
Mathematicatica to graph a nice looking hyperbolic paraboloid as well
as other quadric surfaces like you see in the textbooks.  I've ended up
using ParametricPlot3D, CylindricalPlot, and others but I still can't
get a perfect/textbook example of a hyperbolic paraboloid.  Help??
