Edit - you make it sound as if I should stop looking and take that offer though
I cannot and I will not take the Decision for you, but already in 2022 or so those 32GB ECC UDIMMs were around 100 EUR/each, so if you could get them for 90 EUR/each, that seems something I would consider reasonable in these crazy Times.
About
non-ECC UDIMMs I personally haven't followed up the market much, but I think I saw much lower Prices locally when I stumbled upon them.
I personally would NOT pay for it, but I don't really have a super pressing need: I had plenty of 16GB DDR4 UDIMMs ECC (bought a bunch when they were like 12 EUR / each or so) and thankfully quite a few 32GB/64GB DDR4 RDIMMs/LRDIMMs so if something doesn't fit on one Server it goes on another one and if it cannot be split, then it goes on one of the Big Fat EPYC 7642 Hyve Boys

I think these 32GB ECC UDIMMs are currently more or less around 150-200 EUR/each in Today's crazy Market. Note that I am not commenting on speed PC4-2400 vs PC4-2666 vs PC4-2933 vs PC4-3200 because for my use Case, I don't care too much. I won't be paying double for 5% more performance out of my AM4 Ryzen CPU. That's my humble Opinion at least

I'm not following many Sellers regularly and maybe this one got too popular so it achieves crazy highs, but ...
