ebay, almost all ebay. I haven't been playing all that long and wanted to try out all sorts of different discs and ebay is the cheapest way to do that. In hindsight I shouldn't have done that so early in my career, because for a while it didn't matter what I threw, they all flew the same. It's kinda funny now when I look back and think that my Sidewinder and Beast used to turn pretty hard to the left on me. Plus I play the LINKS a lot and that course tends to swallow a lot of discs with water on 15 of 18 holes!
