Acceptable Clones? Perhaps passed through Gordon?

I'm interested in the "Alternative NRF52840/32"'s that are available.

There are only a few.
52832:
P22 - similar to P8 and Pinetime, can still be found on aliexpress, hopefully still nrf52832
S28 - relatively new find by @yngv126399 https://www.aliexpress.com/item/1005006404242146.html
both are DaFit so no need to take apart, S28 even has screws so easy to open
52840:
C17/Magic3 https://www.aliexpress.com/item/1005005373233740.html or https://www.aliexpress.com/item/1005005935723945.html

And that's about it as far as I know. I also have few spare unused watches still in a box like QY03/P16, DK08, SN80, GW32 or fitness trackers like B5 that I could sell, if you want to experience the older stuff and possibly continue. But as those are out stock there will be no new users except possibly you.
