Alton Brown on "Good Eats" did a show on this, and I have to say that I agreed with him... Using a cast iron pan...
Step #1, disconnect all your smoke detectors.
Seriously though, it was a really tasty way to cook the steak. Both on top of the stove for searing, and in the oven to finish. Just a warning though... It takes longer to pre-heat the oven and pan than actually cook the steak.

Michael Symon does the same.
I've used that method on the gas grill. Keeps the smoke out of the house and drives the neighbors crazy.
Someone had given me a JC Penneys gift card so I went last week to use it.
Found a nice cast iron griddle, 10 x 18 for $20.
That's about half price what they normally are.
Used it on the gas grill last weekend.
About 2 hrs. prior to cooking the Costco ribeyes I sprinkled w/ enough soy sauce to moisten. Coated liberally w/ Montreal Steak seasoning.
Seared both sides , turned down the heat and cooked to med-rare.
Yummy.
(BTW, first salesperson I ran into in Penneys I asked where the Leather Boutique was. She understood my point)
