I can find some for $150-250. Can you share links to less expensive options?

Look at waveshare's website. Get one with a HAT if the description says it needed, and always check out the refresh rate, it varies wildly (from ~0.5 secs to 15+ secs)

I think they are Waveshare's supplier, you might even get cheaper/more specific stuff: https://www.good-display.com/product/6/

Ty. I was also looking for this.

I wonder if the orange tab can be folded over without damaging it.

It can at the adapter board end, but not at the screen end as it has components mounted to it (!).
