If you needed a tap that size, it’s generally going to cost you more than $150…..!
I bet a lower offer would get it pretty easily.$150 price tag seems a little odd to me. A tool like that is worth a great deal more than $150 if you need it. But if you don't need it then it is almost worthless. I might pay $10 or $20 as a curiosity, but I can't imagine ever having a need for it so I wouldn't waste more than that.
