I'm really loving the GL iNet products (US Amazon, for instance https://a.co/d/hSdllBc). I first got one of the little travel routers for a special situation, and liked it so much I replaced a newish ASUS router with the bigger product I linked. It runs OpenWRT out of the box, with easy Wireguard setup; I'm a Mullvad customer, and Mullvad is one of the supported built-in VPN providers, so that was nice.

The one I got is not blessed with a profusion of ethernet ports (4, plus the WAN port), but it's more than was on the ASUS. The mobile app leaves a lot to be desired, but the web UI is pretty good, being OpenWRT. I mean, much of it's goodness is down to OpenWRT, but the hardware is good.

I'm obviously extremely happy with the product. The power plug is one of those "you get a plug for your country," so I assume it'd work in the EU. The country of origin is ~~Hong Kong~~ China.

Got this one (J4125, 4xIntel i226 nics) off of aliexpress, bought ram and ssd locally, no issues with opnsense.
