I'm going to pay close attention to this discussion. I've owned a few variants of the Atari over the years. I no longer have anything remaining in my collection, so I'm setting a long term goal of getting started up again. I'll promise myself to only buy if it is relatively cheap since I don't have that much space in my apartment.
My first ever console system was a Coleco Gemini, which ran Atari games, that my siblings and I found at a yard sale. I was probably 9 or 10 years old, and the 2600 would have been dead for around a decade. I think it cost 8 dollars, and came with 4 games. Joust, California Games, Asteroids, and another title I can't remember.
