I'm thinking about getting my son a used fishing kayak for Christmas. I can't afford a new one. Craigslist had one for $500 which seemed like a good price but it was sold. Saw a few that were cheaper but they didn't seem to be set up for fishing. Does anyone know where to look for a used one besides Craigslist? What brands sell the fishing kayak so I know what I'm looking for? The one I saw was a Wilderness System Angler Kayak.
