I've had good luck with the Le Potato boards - https://libre.computer/products/aml-s905x-cc/ https://libre.computer/products/aml-s905x-cc/ They're available on Amazon, 2GB board is currently $35. Same footprint as the Pi, fits most of the same cases, hats, etc. Decent support forums and community, and the images aren't too esoteric.
