And some of these Lenovos are relatively upgradable too. I'm using a ThinkPad I bought refurbished (with a 2 year warranty) and upgraded myself to 40 GB of RAM and 1TB of SSD (there's another slot too if I need it). It cost me $350 including the part upgrades.

There's also the Framework option now.

It took them a while to, but they finally offer boards based on AMD chips.

I don't need an upgrade now, but I feel a RISC-V framework is feasible once I do.

Where did you find a deal like that? Quick googling couldn't find it for me

Prices seem to have risen a bit since I bought mine. Here's a similar model with a Ryzen 5 7530U for $355: https://www.ebay.com/itm/156626070024 It is certified refurbished and has a two year warranty. It has a SODIMM slot and supports dual SSDs, although not the full size M.2.
