I scored an "open box" Dell Pro 14 Plus on eBay for about 600USD. It's got two USB-A ports, two USB4 ports, built-in Ethernet, 4G LTE, upgradeable storage, and decent Linux support (on Ubuntu LTS at least). The battery is field-replaceable but the 32GB RAM is soldered. (There are other models with upgradeable RAM.)

It's got a middling display (the 2-in-1 display is better) and a somewhat dated Hawk Point SoC, but it's fine for running to a client's site for imaging or network troubleshooting or what have you. I still don't think it's going to last very long, but it's a nice complement to the MacBook I use for client dev work and it didn't break the bank.
