I have a few that I've picked up here and there. Most of them are used but, the last 7800 I picked up was like new and even came with the instruction manual and the clear film still on the metal plate.
Then, there's my LYNX model 2 that I got new in the box.
Atari VCS (6 Switch/wood grain type)
2 Atari 7800s
Atari LYNX model 2
Atari Flashback 2
2 Atari plug'n plays
I think that's it except for a couple of incomplete consoles I have laying around.
