Hi. Yes, we have a 32" Place&Play product but currently can't be used as a replacement for the Joan product line. On the other hand, we have smaller 13" Joan devices available.

At $899 for a 13" display, the price doesn't seem to scale down well to the smaller area. The 32" display is more than 5 times the area, but less than 3 times the price.

Waveshare has a 13" link display + Raspberry Pi hat for $445. That's pretty bare bones — but you could have a go at DIY and save.

I was referring to the Joan display mentioned, but Waveshare is another interesting option. I assume you're referring to this[0] product, which would still require a Raspberry Pi, so $445 is not the total cost to get something working. Of course still much less than $899 when you throw that in.

They have many more options. If you go down slightly in size, it's less than half that price: https://www.waveshare.com/product/displays/e-paper.htm
