I use a t480 for my carry laptop with Gentoo. It’s been solid. Replaced both batteries pretty easily, replaced thermal paste, and it’s good to go again. I paid about 160 got it. I had a t460 as well, but gave that to my gf. Either of those were good and not too expensive for a semi modern computer for general usage.
Gentoo gaming and music production rig working through mostly tty with dwm as a graphical display. I typically stay on tty until I want to play a game, use modern web, or record a song. Otherwise tty with Links browser.
