Yes!
The truth is that i'm really interested in using Sous Vide to cook a whole meal. So tell me about that, if you please. If you should happen to casually drop the number of devices you have, well and good.
Just to fess up, I have two slow cookers with two controllers. Bought because I really wanted to be able to cook two things. I'm thinking, however, of adding an inexpensive immersion cooker, because I want to be able to Sous Vide salmon and my two slow cookers don't have any water swirling action. So, that would put me up to three devices.
