Instant Tent woes

[rsm19699]

Has anyone had any luck finding parts (or creating them!) for broken instant tents? We have a Coleman 6 instant cabin. My husband was airing it out the other day, and the wind knocked it over (no, it wasn't staked down!)… well, one of the hubs at the top snapped and I can't get a replacement for it. Tried the classifieds on here, but can't get into them. Is there a place where tents go to die? Hoping someone knows of a person who collects broken tents, and then sells the parts. Love the idea of an instant, but not too happy that I can't get parts. Granted, the tent is about 3 years old, but it was only used 3 times. We usually use our bigger one. Thanks!
