I bought this one last month when it was on sale for $39: https://www.amazon.com/dp/B0BRK3CYY3
Haven’t deployed it yet, but it’s fully supported by OpenWRT. I would only be using it as an access point, though. My router is a USFF Optiplex with an extra NIC and runs OpenWRT.
That’s what I’ve done for years. Makes managing things much easier, and I run multiple APs (all with the same SSID/PSK) and you can just roam to the best one. One upstairs, one downstairs, one in the weird dead zone in my office, and one on the back patio (it’s not hardwired and uses the mesh connection for uplink).
These are all old Aruba APs running OpenWRT but that’s the plan for this Cudy Model. I may pick up a few more and just replace all of my trusty but very old Arubas.
