This is a deep rabbit hole, I have unfortunately fallen into. IT all highly depends where you are and which retro machinery are we talking about. In general though: - Be prepared that old hardware breaks down, so you need some skills or someone with skills to keep it alive over time. Highly dependent on which hardware, of course. - Ebay is your best bet if there's nothing nearby - Some hardware have modern re-issues / re-interpretations of old hardware. Namely, NES/SNES/SEGA (look into Analogue), Commodore 64 (C64 Reloaded MK2), ZX Spectrum (Next and clones of Next), pocket (analogue), etc. - Emulators are great these days
