I'm looking to buy my daughter a trampoline. It needs to be in good shape with no tears, broken springs or supports. She's just 4 so I wanted to buy her a used one now then when she's older I'll invest in a new one. An enclosure would be nice but not necessary. If the trampoline is reasonable then I could buy an enclosure for it. I don't care how big it is - it could be 6' - 14'. Thanks!
