I have 2 pi4 4GB boards and was waiting forever to get a third to run RAFT based services across.
I gave up last year and bought 3 chinese boards at $60/ea with 2x 2.5Gb Ethernet each, emmc, and a m.2 slot - and they run at half the temp of the pi4 boards.
I never needed the wifi/bt and form-factor the pi boards offered anyway - really no reason to stay as long as you can find software that boots on other boards.
