I have a friend who uses them for his business. If one of his gets twisted up he just repairs it with parts that are recycled from twisted up ones that he found on the curb. Whenever he sees a bent one in the trash he grabs it and has made 2 or 3 complete EZUPS just from ones he found in the trash. He also told me that the ones with the sprung pole in the center handles the rain the best, so if I see one of this on the curb, I'm grabbing it.
I actually have my neighbors first up in my shop for repair and am waiting to see one in the trash to get the parts needed to fix it.
