I got an Elektra in 2011 for $25 off Craigslist from a guy that bought a storage unit of games. Needed a MPU and backglass (still looking for one).
Addams Family in 2013 from a neighbor that saw my games in the garage for $2600, nice condition.
This week I got a FREE Fire! from my sons Cub Scout den leader who is getting ready to move. Dead batteries and some display issues.
