I bought a set of two amazon eero pro 6E mesh routers from amazon on June 4th of this year for $240. They were on sale then, they're now $350 (see amazon link below). Used for less than 3 months, they're still basically new. I don't know what the issue was, but I had intermittent issues with them, random delays before connecting to the internet and weirdness with scheduling downtimes at night. Most of the time and with most devices, they seemed to work perfectly. Main issue seemed to be with Xboxes. If you don't have an xbox or are more patient than me, maybe they'll be perfect.
They come with power plugs (not shown in picture) and ethernet cable. I factory reset them. You can try them out for a week and if they don't work for you, I'll give you your money back.
