I use a modified Alton Brown method for sirloins -

*rub olive oil and salt & pepper into both sides of the steak
*heat up a baking pan in the oven at 500 degrees
*heat up a frying pan on high for about 5 minutes
*throw steaks into dry frying pan, 2 minutes on each side
*then put steak into baking pan that is in oven - bake 5 min for medium

easy and good - but OMG so much smoke gets generated!
