It's not really that expensive, the video cables for game consoles don't cost that much money, and a lot of consoles used the same composite cable for multiple consoles. I never owned a PS1, but the PS2 and PS3 use the same composite/component cables, and Nintendo had the same one from SNES all the way to Gamecube. The only expensive console cable I can think of is the Gamecube component cables, largely due to rarity, but finding a Nintendo composite cable shouldn't run you much money at all. Or you can buy multi-console composite cables, so you just have to swap the video cables out of the console itself, as most people never owned composite switches.
