Just found this on the web. Looks like the company wants to sell everything it has before October 1st! So, if you're in MN and looking to snag something, this may or may not be your ticket:

I see they list Frogger, Donkey Kong, Arkanoid, Defender, Space Invaders, and Tempest, just to name a few. Unfortunately, my wife would kill me if I grabbed one.
