I would buy another one if the price was right. The first one I got was low priced. I think that it is rare enough item that no one is looking for it so it doesn't drive the price up much. There is also next to zero information about it other than what is in this thread. No ads from old magazines, no commercials or any mention of it in catalogs. I think it was probably a repair tool used by Sears Repair Centers based on the stickers having Sear Parts numbers for the Atari Controllers.
