I have an Anova unit and it is rock solid. Cost if you sign up for their mailing list (Add them to your spam list) is $130.
Forget everything else you can do with it, you can pasteurize eggs and make your own mayo/aioli.
Takes 2 minutes to make it. It is sooooo much better than the store bought chemical soup.

Seriously, put a unit on your Xmas list. You will thank me.
Veggies are a PITA Sous Vide. Asparagus IMHO is better steamed 5 to 7 minutes depending on the doneness you like if you are going for that texture/taste profile or roasted (YUM).
I’ve been eyeing that Anova unit for three years now. I’ll probably get one eventually but my main cooking focus lately has been on Southern barbecue. I’m approaching perfection with my ribs and Mrs. Chandler needs some of my smoked pork shoulder for her Christmas tamales. What I really want to try is spatchcocking and smoking a turkey. I should be able to pick up a bird cheap soon and cook it in late December —
not too close to Thanksgiving.
