I've heard good things about the bananapi bpi r3. Been meaning to get one myself, and you can find them in kits with cases, antenna, power supply etc for maybe just under 100.
The R4 is around the corner and has the option to support WiFi 7 via expansion module. I think it's still awaiting upstream support for openwrt, however. If you don't need WiFi 7, the R3 is a solid platform.
