I managed to score a basic CDi 200 unit from ebay for just $39 with free shipping.
I took pics but forgot to transfer them to my flash drive for upload.
The CD tray is very loose and actually slides out of the machine if turned on it's side but besides making a noise like a dying whitetail deer when sliding in and out it seems to work fine.
I tried out Tetris and it ran perfectly.
The CDi remote (which I assume is the original) is powered by 2 AA batteries and is pretty beefy. It's amazing responsive even when not pointed at the CDi. It's got a big clunky thumb stick that is different from any other controller I have ever used. On the main menu bootup screen it acts just like a mouse.
The machine itself seems like it's in excellent condition and it even came with the original manual.
All I need to do now is keep looking for discount software for the system!
