Our son did end up getting us an Anova wifi model for Christmas. So far I've used it for perfectly poached eggs, incredible chicken Tikka Masala, the best pork tenderloin either of us have ever had, and yesterday I turned a bag full of frozen Thanksgiving turkey bones, water, vegetables and "aromatics" into a super rich turkey stock.
For our son's birthday dinner, I'm actually planning a full Sous Vide menu -- SV garlic confit with crusty bread for an appetizer, SV stout glazed beef short ribs over polenta for dinner, SV Chocolate pots de creme for dessert, and a SV maple-bacon infused bourbon to end the night.
One of these days we'll get around to actually trying SV steaks...
