Hello,
I'm also a newbie, but recently got the Anova and am loving it. Couldn't be simplier to use and stores easily when not in use. I've played around with different containers (most of my pots seem small), but I think I've hit upon a solution for when I do a big batch or need 24 hour+. I was lucky enough to receive a gift basket from Omaha Steaks that arrived in a large syrofoam cooler. The walls are just thin enough to attach the Anova, so I cut a whole in the top and voila! This has been going now for 2 hours at 185 degrees and the outside is cool to the touch...
