I agree cast iron is the way to go. It holds the heat and will last forever.
Don't use Teflon though, it can chip or peel under high temperatures and doesn't give the same grill marks.

Cast Iron by: Chef Matt
Cast Iron is the way to go on this one for sure. Very heavy gauge steel will work too but over time it will distort and warp. The problem being that it does not cool or heat evenly each time you use it. This link will take you to a site that has all things cast iron. Good luck and I hope it helps. - Chef Matt-
