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...

At $20, just buy from LCSC-

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.
