I recently upgraded from an S10 that I was very happy with to an S20. I bought a good condition used one from Cex and am very happy with it, you wouldn't know it wasn't new, and far more reasonable in price. Good size, not too big or too small, and I don't need the latest phone when I mostly use it for WhatsApp and photos. 

I would have happily stuck with an S10 but good condition used ones seem harder to come by now.

I have an S10, great phone but the last system update I had was on 31 March 2023.  So if you are going the 2nd hand route, check how long it will still be getting updates.

I'm in a similar position, but I'm checking the security support on each model that is of interest before buying this time:

It is also worth checking some of the YouTube review channels too.
