It's important that when you try a cast iron skillet, that it be properly seasoned. Some of the name brands come with instructions on how to season. And as Teamfour said, you are never supposed to wash the pan with soap and water unless you want to re-season it. Just rinse it out with hot water while the pan is still warm, and dry with a paper towel and rub some vegetable oil in it to prevent rust. Over time, this process will seal the pores and the pan will become a non-stick pan, plus adding flavor to every dish you make! Go for it!
