I got lucky with a recent purchase. I wanted to buy a second Switch for hacking and I found one new, cib with firmware 1.00!
After reading what I could do with it I've now ordered the Japanese Puyo Puyo Tetris to make use of the nereba exploit. (It will take almost two months to arrive from Japan, though)
I was planning to buy a hackable Switch for a while, but this was really dumb luck. I could read the serial number in a preview pic of the box and immediately bought it.
Interestingly, my first console (Mario Odyssey bundle with the red Joy-Con) has a warmer screen than this 1.00 Switch. It looks like they improved the screens between the first batch and the later ones.

I wanted to get a second Switch for hacking so that I don't have to worry about getting banned on my main console which I use to play legally purchased games. I'll use the 1.00 console for retroarch only, I'm not interested in piracy of Switch games.
I'm so happy now!
Perhaps I'll sell my old Switch and try to get a Lite or the new improved model in the future.
Edit:
Is there anything I can do to make the pics smaller so that they only expand by clicking on them? I'm sorry, I didn't expect them to turn out this big.
