With time on my hands, I e-mailed every bike shop in both Richmond, VA, and the Hampton Roads area, asking if anyone had a used truing stand. Probably about 30 bike shops altogether. I only got one positive response, but that was all I needed!
Turns out a small one-man shop, near VCU in Richmond, had an extra...a Bike Hand YC-512N. He sold to me for very reasonable money, and it has worked flawlessly.
A sad conclusion is that about two weeks after picking the truing stand up is when George Floyd was murdered, and this guy's small bike shop was totally looted. After mostly servicing bikes in his neighborhood, he currently remains out of business.
