> We used 9 Alfazeta panels in a 3x3 grid or 84x42 discs. Each board has (2) 28x7 panels.

So how much do one of those cost? The website (https://flipdots.com/en/products-services/flip-dot-boards-xy...) notably has no prices listed.

This [1] page talks about 500 EUR per display which would result in about 3000 EUR for a 3x3 grid or 1.27 EUR per pixel.

I love the idea but that's WAY to expensive for me.

Each board is, as of this year, 220 EUR per 7x28 panel. Still expensive! But specialized.
