That's the one! You don't necessarily have to get a bunch, just swap out SCART cables but keep them plugged in at the console end.
Would it matter if the SCART cable was NTSC or PAL? Or can cables actually be NTSC or PAL? Also, do all the systems you listed with RGB have SCART cables?
EDIT: And on that converter in the eBay listing, I can't see any audio output. Am I missing something?
