I bought one of these surfboards for my wife a few years back and, on a smallish day, I took it out instead of my short boards. I have to say I was blown away by how good this 8-foot piece of Taiwanese foam actually rides...
It's the $100 Wavestorm from Costco, and though it takes a certain lack of self-consciousness to ride one, I can't deny its prowess, though I'm pretty sure that was an accident on the manufacturer's part.
