There have only been 6 Torus(s) come up for sale in the last at least three years.
I had bought one 20a+10a,a friend bought two-20a,and one 60a just sold on audiogon and there is a
15a 120v for sale on cam.
You see tons of well known conditioners on both sites,yet the Torus is almost non existant(for sale that is).I do know for three of these the sellers went to a bigger Torus as they needed more reserve power as they had went to biggeramps:4's to 7's to 28's.
FYI, I was the lucky recipient of that 6th Torus (RM-15), courtesy of Dr. Bill Gaw via Audiogon auction (yes, he actually parted with one even before he got into the PP2000).
That was the only way my budget would allow me the purchase - thankfully, there's really nothing to wear out in the Torus, so I bought with confidence! I spent months searching Agon daily. After experiencing the effect, it seems clear to me why they don't come up for sale very often.
