You never know. Might have been great childhood memories for someone with deep pockets.
The ones that bug me are the ones that try to pass off value by ebay listings. A local selling several machines on CL said "I know my machines are worth this much because..." and points to current ebay listings. Just because somebody listed it for this much, doesn't mean it will ever sell for that much.
Now, point me to some completed listings where they actually sold, we have a more realistic number to work with.
