I have been collecting Atari 2600 stuff for around 15 years or so and have a pretty extensive collection, so yes, I am well aware that it is rare. I only collect NTSC stuff, so I would be looking for an NTSC version. I didn't specify cart only or CIB because I wanted to see if anyone responded, and if so, what they had...of course CIB in good condition would be awesome, but I'm not holding my breath.
