I bought a MacBook Air M2.
As of writing, it's very affordable with the 16 GB RAM, 256 GB SSD, 13.6" model available for $750.
As of writing, also Asahi Linux doesn't support anything newer than M2.
If an old CPU would work for, I highly recommend and older Intel based Mac. They run amazingly well with Linux and, as you say, the “experience” is excellent.
The MacBooks with T2 chips are a bit less ideal as they require a special kernel. And the 2020 MacBook Air has crappy thermals and runs up the fan. There is a version of EndeavourOS that installs everything ou-of-the box through. The WiFi in these old Macs is out of tree but many of them require the Broadcom wl driver which Arch Linux distros ship by default. Depending on model, the out-of-tree FaceTimeHD camera module may be required but it ships in Arch distros as a DKMS packages. So, again, everything just works.
They really are a joy to use. I bought a 2013 MacBook Air a few years ago for less than $100. I bought it to go on backpacking trip because it was light and I did not worry about breaking it or having it stolen. I love it so much I still use it several times a week and it still amazes me what it can do.
