If you buy the TC2 and use the stock firmware, you get a decent, albeit flawed, tool for the price. But if you are willing to risk "bricking" it, void your warranty, and solder a few headers, you get access to a device that improves with time—a rarity in consumer electronics. The TC2 has become less of a product and more of a platform, held together not by FNIRSI's engineering, but by the sheer stubbornness of the open-source community.
