Craig,
I'm only mentioning this because I can't tell from your picture, but a Sous Vide in a flat bottom pot can and will crack a hard surface countertop. If you aren't already, something underneath the pot will save you from my disaster.
Also, I've been putting the meat with marinade in the bag overnight in the fridge and then just popping the bag in the Sous Vide and it really amps up the flavor.
