Hello!
You can find some mass produced screens, there are many of them. Now will you be able to use them? That's
another story. If you buy Raspberry pi screen, you're almost sure that there will be some geeks around who
publish source code to make it work. If you buy an anonymous screen somewhere in China, you will have
to start from scratch. Now it's up to you. You can find a mass production screen around 25 Euros or maybe
a bit less. You will have to do everything by yourself from the 1st pixel. Is it worth what you will save?
Beside this, if you buy anything in China, you will have no warranty at all and the shipping fee might also
be expensive. Or you buy 100 of them and resell what remains... around 50 Euros with source code.
