Not the cheapest brand but is a great price for a stud finder that actually works.
Edit: Slightly cheaper at $73.28 if you select to buy from Amazon US from within the Amazon AU page. Free delivery for prime members, expect later delivery date for this international delivery.
I've got a Zircon one from Masters days which I like. It hasn't gone detecting every wall as a live wire like some of the comments about the Stanley one lol.
I tried one of these bar style ones except by a Ryobi and I didn't like it. Sure it would light to the stud but I didn't think it was that hard to do with the traditional one, and it was lacking the AC and metal pipe detection. Felt like a downgrade, less information.
