If only I could find ~30 Raspberry Pi4, I'd use them for a digital signage system. (For availability tips or suggestions, I would be very grateful!)

If its just digital signage why not use RPi3s?

Mostly because software was designed as a burnable ISO image tailored to Pi4 specs. I could also make a Pi3 version, but availability looks quite the same if not worse.
