OT: Casting figs

There's a local hobby/game store near me that is
getting into the casting business.  I have some idea
for some 6mm Sci Fi vehicles, and would like to try my
hand.  what type of wax or medium is best for doing
the original to submit for creating a master, and
where can such material be found?
