I started out buying expensive home Wi-Fi routers, and I now have a box of expensive home routers I've decommissioned because they have vulnerabilities and stopped receiving updates. Probably well over ~£1000-2000 spent on them over the past ~decade.
Next I switched to separate Router/Switch/AP and started with a Ubiquiti EdgeSwitch 8 POE, EdgeRouter Lite 3 and an AP-AC-Pro. Later I added a EdgeSwitch 24.
Recently my EdgeRouter kicked the bucket, and wanting to be entirely free from manufacturer updates so I bought a Protectli box, flashed it with Coreboot (instead of AMIBIOS) and installed pfSense. I still use the AP-AC-Pro for now but will look for more open WiFi AP options once that dies or I move from my London apartment to a bigger home.
I say "if you can afford it" because the Protectli box came in at just over £500 once RAM and SSD were added (I got the i3 model), the AP-AC-Pro is ~£120 (IIRC) and the EdgeSwitch another ~£150. This isn't "reasonably" priced equipment for home use, nor would I recommend Ubiquiti of late, but it's working well for me at the moment.
