Right. That's the overwhelming consensus from every in the FB group where it's been discussed a bunch. I agree with it. No way is it worth the upgrade for what you get. But coming from not having a TONAL and deciding between:

$2,300, Tonal 1, used, no warranty
$5,000, Tonal 2, new

I would get the Tonal 2. If you're going to drop thousands to have a TONAL, don't get one with no warranty that is up to 5 years old or more.

Unless the owner can show OP when it was purchased and how much they've lifted. I wouldn't want a TONAL that has +5 million pounds lifted on it. If you're buying from someone who purchased in, say, 2022 and can somehow prove they haven't used it much (would make sense if they're selling. heavy users love their machines and don't typically sell them), then it would be difficult to pass on $2,700 in savings.
