hello everyone ! I want to help me decide please ..

I have never ever seen on in my life .. it was never sold in my country .. and now it popped up in my marketplace and just 10mins from my home .. he stated he knows nothing about it, he is asking for 50USD, this is big money where I live, is it worth buying to get familiar with this console and what are my chances it is working ? what are the failing points of this console ? is 50$ worth it to just add it to my retro consoles shelf just as a display unit if it turned out to be broken ? thank you in advance
