I remember when I bought my set, from HJE. I think they were $100, and I figured, it was more of a collector piece then a use piece, and they were only going to be going up in price. Then there is a part of me that wanted them to compare with other flare nut wrenches I have used, or would like to try (still want to try Williams and Wright just no real project time). Started out with a closeout Kobalt JH Williams set, that gets mistaken for Snapon, then built my Snapon set for around $8 a wrench on Ebay years ago. Looked on Ebay due to this thread, and couldn't believe what they were asking for them now.
I find it amazing what all people collect. I am around autographs and a bunch of sports crap all day (my view), and was so happy to see things like a golden glove quit sitting around being a dust catcher, yet those wrenches, which may actually get used on a friends project soon, I have no issues with sitting around being dust catchers. Sometimes I think there are a lot of things I should sell and put that towards other stuff.
