@mcc Dunno if the deals are good or bad, but we have a ThinkPad T14 (no idea what generation) in the house and it's pretty good for Linux. (personally I like T14s better - the T14 feels bulky. But there's a price premium).
I seem to recall I had to mess with Debian images with additional non-free firmware to get it going (for the wifi, I believe), though
I'm not sure if ThinkBooks are good - I stay away from anything Lenovo innovated after they bought the line from IBM.
