There have been several that I regret letting go of. The big ones would be:
1. BSD - An absolutely gorgeous example, and it was my first game. I sold it to help fund my Io Moon import.
2. Mephisto- A very rare game and it had an almost perfect cabinet. I traded it to a friend for TAF. At least I can still visit it. 
3. CP- This was a sample game from Switzerland and it was in pretty nice shape. I sold it way too cheap.... even by 2007 standards.
4. RBION - A super low play HUO example. Looked like it came right out of the box. I lost my butt selling this many years ago when everyone thought the game was a dog. No one wanted a RBION back in those days! Sold it to pay some bills.
