A used one in your area, so long as it’s newer (2021+)
I would recommend using Linux on it instead of ChromeOS, if you’re a little more technically inclined. ChromeOS is fine but it limits you to just the Google ecosystem whereas Linux allows you to do things with it like a normal computer.
I took an old (2017?) model and put a super lightweight Linux distro on it and use it as a little administrator device. It’s got good battery and acceptable processor speed, but it’s severely limited by CPU cooling and storage.
