I got the t450s recently off eBay. I would not make the same purchase again. Instead I would go for the x series models. This is because the keys on the t450s size laptop (which is larger) are too far apart for coding. Then there's the tn panel screen, the viewing angles are so bad that at 14" you have to choose whether you want the top or the bottom of the screen to be clearly visible -the other side will appear washed out. I never noticed this on the X230 which probably has an equally shitty screen, because its size is just right to never be an issue.

If I could return the t450s I would go for x240 or x230. Upgrade the battery, and toss in SSD if it doesn't already have one.

Also, check out mini PCs like the gigabyte brix. I use them as headless dev boxes on the local network. Run 24/7 without issue for months now.

I already work on a full size keyboard. So I guess keys being spaced out won't be an issue. Also, a refurbished t450 would be too expensive for me anyways. Sticking with t420 or t430

X230 sounds to be up your alley then which you can find for as low as 200$. If you're a hardened emacs user, your fingers will thank you.
