I've been digging on Sous Vide with my steaks.  Seal them in a ziplock bag with a bit of garlic, black pepper, and some fresh thyme.  Drop the bag into a water bath at 131 degrees (try and get all the air out) and leave it there for about 45 minutes.  Pull it out, throw it on a screaming hot grill, just to get some char marks on it.   Perfect med rare all the way through.  Fan-damn-tastic.   
This is a great primer on the technique.  Most tender steak you ever had.
