I've had people fly cross-country (twice) for these steaks and it's really not all that hard. But it makes for an expensive summer season with lots of entertaining on my deck.
One guy was mystified as to why I wasn't using the popular Morton's method of high heat and turn once. Then he had one, came back the next weekend unannounced "just happened to be in the area" and tried to bribe me with a bottle of Santa Rita Reserva Cab (I know cheap wine, but good). Too bad I was out of steaks.
And yes, I usually get the on-sale cheap steak at the local grocery. So long as it's decently marbled it doesn't really seem to matter much what I get so long as it's not skirt or flank.
