I got my THS-02 through one one of my best deals ever on eBay, loose THS-02 and sealed THS-02B with a free loose classics Prime for around $100 a few years ago
Hybrid Style is still the great lost lamented TF line, for me. THS-02, particularly, is superb.. how I wish there had been a Hybrid Style G1 Megatron to complement it.
