[Jukebox-list] Rock-Ola CD Fireball

I've never seen one of these before. From pictures it looks something like a CD NSM with the two vertical stacks of CDs. Are they problem machines? Do I want to go out to attempt to fix it and learn in someone's house. Did they make other models like it or was it a flop and discontinued? My gut is telling me to pass on it. It is the floor model if that makes a difference.

I think I'm talking myself out of it. I have 50 to 75 total service calls and machines in the shop waiting for their turn.
