I got mine from homeofpoi.com.
I got a practice one and the actual fire dart & the only thing that sucked about the fire dart was when I took it outside to try it just to swing it around to see how it felt the chain at the end snapped really easily. I replaced it with a length of chain that I had already & it was fine after that but if that thing would have been lit I would have sent a flaming ball flying at someone probably. The practice one was 20$ & it's just white nylon rope & the fire dart is kevlar & was 70 or 75$. It came with a fire safety dvd too. The practice ones are different colors too.
