I've got this old one hanging around. There is no physical damage to it, but has yellowed with age. Working? Well sort of. It always turns on, but sometimes it's difficult to get cartridges working. (Jam a piece of paper in the sucker, and you may get lucky) Not really sure what's its worth. You should at least have pay for shipping from Canada. I also have a few games, and extras for it. If interested in them, let me know, and I will make a list.
Best regards
