On Sunday evening, I did some thorough searching on on Ebay (US) for all the 32GB DDR4 EEC REG that I could find at ~$85 or less. I kept to Buy it Now Listings that had multiple sticks to sell and weren't 3DS/TSV.
I found a half dozen or so between "Components and Parts...--->RAM" and "Server Components---> RAM" sections. But, it was almost midnight when I finished, so I knocked off and thought I'd come back the next morning to decide which to purchase.
But, by the next day at 9:00am they were all gone! Every last one! Even a "new" listing with over 100 on offer was sold out overnight.
