For those located in Germany, the D-Link COVR-X1862 are very cheaply available at the moment (€ 40 for a pack of two at MediaMarkt / Saturn).
They are MT7621 + MT7915 AX1800 devices, similar to the DAP-X1860 repeater, but with external power supply and two Gigabit ports.
Support should be ready soon, only thing missing is the encryption for factory image (but it can also be flashed with an unencrypted image via bootloader, just like DAP-X1860).
