How exactly did the author get the panels? I've looked into stuff like this before and it's basically impossible to source outside of things like eBay. Unless you're willing to buy industrial quantities at industrial prices.

How did they buy them, and for how much?

I got mine off eBay, but you can get the same panels from AlfaZeta. There are some more affordable options like: https://xqd-led.en.alibaba.com/productgrouplist-936470954-2/.... I do mention in my post that I would like to see these panels become more affordable for hobbyists. If anyone wants to collaborate on this, please contact me!

Do you mind sharing how much the panels cost from eBay?

I feel like that's a key data point that would help people decide if they want to explore this further.

Speaking as someone who also recently purchased these panels (and read the second paragraph where they mention where they got them), they're from the company AlfaZeta.

They build and ship from Poland. They don't have a publicly available price list but they cost approx 220 EUR per 7x28 panel. Expensive, but few places still manufacture them.

If you continue reading the post, they also link out to other manufacturers including ones on AliExpress that seem to be cheaper.

What's wrong with eBay?

Nothing - just might have to wait a bit for them to come up.
