Cyldinder Head Stands

I'm mostly a "keep it simple" kind of guy. I've used those stands to great effect for many years. $20? and they're plated, too. Why try to reinvent the wheel?
Like 30-35 yrs ago, I was at the Portland Swap Meet, and some guy had a pair like that for sale. I tried to talk him down to $15, but he wouldn't budge at all. I asked him what they were for (I knew, but I suspected he did not), and he said he didn't know but they HAD to be worth $30. I circled back several times that day, and tried him several times, but he never budged, hahaha.
