I stumbled upon a Keeney Rainbow recently as a barn find. It was working very briefly but after putting a few balls in play the game froze up with the motor running and each time I plug it in its in the same state. Its a bit beyond my capabilities to fix it. I don't mind having it as a display piece next to my other working EM's but would rather have someone else get it running and make it a proud part of their collection. Backglass has a little flaking. I sealed it when I purchased the machine. I can provide pics and a video if anyone is interested.
