the cast iron hot dog cooker

There aren't exactly any cast iron hot dog cookers; The closest you will come to one is the above pie iron, which is specially shaped for hot dogs and sausages.

But I recently discovered that the wonder skillet is an excellent stovetop hot dog cooker.

It perfectly fits up to four standard sized hot dogs. I'm not sure about "bun length" hot dogs; maybe two if you put them diagonally.

Just heat up on the stove and cook the hot dogs. Be sure you turn frequently, to avoid black spots on the dogs.
