I've bought 2 of these routers from this link. Direct searching leads you to a $400+ link.
Cheapest I can find at the moment for a router that is comfortably handling multiple LAN and wifi connections, running AI mesh, having a torrent client running in background with a raspberry pi, serving plex 4k to multiple devices.
Has an easy to use App and webUI. Can easily customise DNS, port forwarding etc.
QOS is reportedly buggy and caused an issue blocking my nvidia shield pro when activated for streaming.
Edit. Cheaper on Amazon now (for non AU version). See comments below
