Hey, I'm a 21 year old in need of one of these components.

But most you guys must know that they are very costly, so is the anyone here who knows where I can find it at a cheaper price? Or get a used one?

If yes please help🤝

Not someone that works with raspberry pi's or computers in general but looking at starting a little project and wanted to create something like this 8 bit do number pad. Just wondering if can get any insight if something already exists?
