Hi! Initially, excuse me for my English, I'm Italian and I can't speak English very well

I would like to know some informations on the building of an Arcade "machine" and an Arcade controller (i'm a nostalgic of the arcade games that I played when I was young ahahahah) with a very low budget. Which alternative do you advise? Raspberry? Or a cheaper alternative (if it exist)? How much should I spend? Excuse me if I'm vague, if you want to know other informations, ask me.
Thank you!
