I can recommend and own a SBC/router made by https://www.gl-inet.com/ https://www.gl-inet.com/ I have the GL-MT300-A and it's actually an upgrade over my older router. It runs OpenWRT, and has enough power to run a couple extra services. At the time of purchase, it seemed like the best deal (~$30) for the feature set it had. They have a few different models with different options depending on what you need. They also seem responsive to questions on their support forums, and have their products available via Amazon if you want it faster.
