I've been looking for an option for searing all the meat we have been cooking up with the Anovo Sous Vide's we bought a couple years ago. It appears these two brands are mentioned frequently in reviews/youtube/ozbargain posts as one of the best options for butane torch searing Sous Vide meat. I've searched for these items before and often found it difficult to get them at reasonable prices delivered to (or within) Australia.
I stumbled on this online while debating whether I really needed that weber, the reviews seem great and they fit the brand recommendations. The compatible torch is the BernzOmatic TS8000. You can find it for around $110aud delivered online on ebay (thanks TEER3X, See comments).
You will need the Torch and the Attachment!
