What I did when I was looking for a newer router to run OpenWRT was to look at their supported hardware list, narrow down to the ones with recent WiFi protocol support (in my case, WiFi 6), then compared prices. I was able to buy a used Belkin router for $20 on Ebay that did the trick.

Have you checked out Mixxx? I haven’t used either of them myself, but I’ve read some people say that Mixxx is good and that it was patterned mainly after Serato.
