lenovo duet 3 with postmarketos. Under-100 on the refurbished market, comes with a keyboard, reasonably powerful, good screen. It's a sleeper deal right now and the postmarketos support is _very_ good. Everything but the camera works. Even detects the keyboard being connected properly. I recommend the phosh version (that's your tablet DE). Postmarketos has come a long way and really just feels like a polished desktop linux now. There are tutorials specifically for the duet 3 / postmarketos. Basically you will set the tablet to dev mode, enable usb booting, boot the usb, then overwrite the EMMC drive from the postmarketos usb. It's almost as easy as a regular linux install.
