Opinionated list:
A few months ago, I bought a used ThinkPad T450s for about $190 (including shipping). Durable, but I have had some strange hardware issues. A track pad button will stop working randomly, but a restart will fix it. I also had an issue with ghost pixels, but that seems to have stopped. I'm running GNU/Linux, so ¯\_ (ツ)_/¯
(I do prefer workstations for development work TBH.)
