Update! I've revised my upcoming Bricklink order a bit.
First, I'll be getting all six Toa Mata, plus a second Tahu, Gali, Kopaka, and Lewa. In addition, I'll also be getting a gold Hau and a silver Miru. With all that, my toa mata collection will be complete, and I'll also have all I need to build the two Toa Kaita. In addition, with what money I have left, I'll be getting a Vahki, Whenua Hordika, and Carapar. That's all I know I can get for certain. I'll decide what I'll do with any money I have left over at the time.
