I recommend looking for a model from a couple years ago -- long

enough for user reports of any issues to be findable by Google.

At present, large organizations are replacing relatively new laptops

that won't run Windows 11 (e.g., some models of Dell Latitude 7480, 

but see Setting up Linux in 7480 - Dell Community) so you might want 

to check Dell's "refurbished" systems or eBay.  One problem is that such

laptops are often sold with a variety of wifi cards, so you may

need to swap in a more linux-friendly component.   Higher end

Dell and Lenovo are generally easier to service than some

consumer laptops, but you can often find online instructions for 

SSD and wifi upgrades.
