If you're looking for a fairly cheap one, Lenovo *00e series has been good for me. EXCEPT for the 100e, that has a design flaw that makes it easy for pins to cross in the USB-C charging port, permanently bricking the device. So except for the 100e, that series is great.
Walmart's marketplace has a 500e listed for $92 right now, and it's also mostly compatible with all operatimg systems via Chrultrabook.
If you're at all interested in running other operating systems on a Chromebook, then I'd recommend checking out compatibility in the Chrultrabook docs [1]. Nearly all devices listed there are verified to support Linux, albeit many have issues, usually missing volume limiter support, camera support, or fingerprint reader support. And keep in mind that ARM CPUs are currently entirely unsupported.
Also, it's absolutely hilarious to me that some Chromebooks support macOS better than they support Windows or Linux. In the vast majority of cases, though, Linux has the best support.
