Well, my “separate the broken glass from the digitizer” attempts using the kits from ExpertCellDIY failed (I had a few to try on, alas it is a tedious job and I did read that the glue used on older devices such as the Pixel 3a XL I was testing on was a lot harder than newer glue… possibly this caused the problem, but the result was I thought I was successful on one but when powering it on I was greeted with the 1000 sparkles and flashing colors of a broken digitizer 
)
For these older devices, however, I was able to obtain refurbished (so genuine but not new) full OLED displays (with no scratches) for about $45 USD. I also obtained new batteries (3rd party but larger capacity than original, reputable 3rd party manufacturer) for under $10. So for $55ish each device I now have 3 Pixel 3a XL with scratch free beautiful screens and fresh batteries.
Now that I have set up “OTA updates” for my Unofficial Pixel Builds, this means these phones will get OTA updates too. So I think they are at the level that I am happy to offer them for sale. It won’t be as cheap as if I would have replaced the glass without replacing the full OLED display, but they still will be a good bit cheaper than other devices I have listed.
Look for them in the coming week-ish on https://openmobile.us
In addition, since iodé doesn’t have capacity to offer an official Pixel Tablet build, it is a good opportunity for me to sell them as well. De-googled tablets are not that common. And again I have OTA updates for them using my unofficial builds.
