Here in the midwestern USA, I see them in independently owned used game stores and record stores that sell used games as an alternative to buying a used NES, so you can get a brand new system for a slightly lower cost than the pre-owned one that often needs new pins. Lately, though, they're usually the triple machines, the ones that play SNES and Genesis/Mega Drive games, too, so I'm not sure if that counts or not. They are at least machines that include current Famiclones, though.
