If you don't have the means to go to a good butcher and buy a good steak and get it chopped up, steak tartare probably isn't a viable menu option.

If you're just all about the undercooked meat thing and aren't dead set on a particular recipe, buy the cheapest steak you can find from wal-mart or wherever, cut it into bite-sized pieces (or don't) and briefly sear each outside surface. Voila, beef sashimi, likely to be more or less safe.
