4's are very scarce but 400's are fairly easy to find. They are around $80 and they are basically a pi 4 with 4GB and a keyboard. A reasonable alternative unless you need the SBC form factor. There is a $100 combo kit that includes a mouse, power cube, and SD card with the OS on it. I just wish they had made the keyboard include a built-in trackpad so you'd have a reasonable laptop alternative by just adding a screen.
