Sous Vide Duck Confit

I love duck confit but it is easier to buy D’Artagnan’s duck confit esp now that it is carried by Giant Grocery store, same price as from D’Artagnan without having to pay for shipping.
It is hard enough cooking per their recipe which takes around 3 hours 30 min, and having to break the crust about 7 times., adding demiglaze to ensure the cassoulet does not dry out.
I even remember having to cook it more than 4 hours as D’artagnan does not recommend adding bread crumbs to make the crust which is a lazy way of getting that fantastic crust.
I do follow their recipe except I do not use coco tarbais beans ( too expensive) nor fresh fave beans, but rather white cannellini beans.
I have 6 D’artagnan’s duck confit in my freezer, but the problem is tracking down some garlicky sausage which Giant does not have. I the to go to the Farmer’s market in DC for them. Had purchased their chicken sausage from Giant, but did not like the taste , too bland! It is also too hot to have to turn that oven on!
