Fansproject have only made the Cliffjumper kit, and the upcoming City Commander kit. And you won't find it for sale at TFCon, since it won't be released until September. Yup, you won't find it for sale at the TFCon.
Oh, and about the price. These guys are just fans, not a business like Hasbro, who can produce a lot more and sell for less. So it's hard for them to sell it for cheap, and make their money back to put into future projects like this.
