Amazon had brand new 2nd gens for $79 about a week and a half ago. I haven’t checked lately cause Apple replaced my gen 1 after the 17.0 update killed it. If they didn’t replace it that’s what I would have gone with.

I have 2 1st gens and they work perfectly fine for me. I don’t like FaceTime so that wouldn’t matter to me. If that is a must have then go for it.

Why is the need for the upgrade?

The second gen 4K AppleTV works very well. It is slightly faster and can use FaceTime. Just another option if you buy used.
