WaveShare has e-paper modules between 5" and 7" costing around 50 EUR. You can drive them either from a Raspberry Pi or a ESP8266 microcontroller.

We're using a small one as an instrument panel on our boat https://github.com/meri-imperiumi/dashboard#readme

Nice project! Yes they are indeed cheaper. It's really up to your taste. The device I'm using is already in a casing and comes with a sophisticated software that can render any modern HTML5 on the device with full JS support.

Like say, running Firefox on a raspberry pi?
