Let me know if the barcodes are anything but unique/perfect. This has been the case with many vendors, but these chips are cheap enough that you can try 50 vendors.

Will do. Not too worried about trying low cost parts to gain some minimal confidence in a possible source, they're compelling for weekend side-projects at least.
I've previously struggled to roll the dice for higher end parts as the cost difference isn't as extreme and had some obvious reballed parts a few years ago. If they're OK then their $20 XC7K325T will be at the top of my list...

That's low-end Zynq and Artix and I'm thinking more >676 Kintex, though I appreciate any discussion on sourcing.
In the way that that Aliexpress vendor lists the 7010 parts at 1/10th the price of LCSC, some of their $20-60 listings are also shockingly cheap in comparison.
Ah, missed the K! For the K420T, I pay around $30-45 from CN (not Aliexpress) sources with original barcodes (but these vendors are quite a bit harder to deal with.)

I have some obviously reballed (but well done) aliexpress XCKU5P's that I got for $55 a while back. Haven't tested yet but the price was so good I couldn't resist.

I’ve been bitten before but the risk/reward is probably worth it for parts like that.
Thanks for your write-ups btw, been following glScope development for a while.
On the chance they're half reasonable, thanks for the link.
