I'm only collecting Yamato's and Takara BT's right now.
With my Takara Binaltech collection I made the small mistake of NOT picking up Takara Lambor. Instead I saved some cash and picked up a Hasbro Alternator.
But I just got my BT 03 and 04 so I'm pretty much up to date.
With my Yamato collection I'm looking around for a Quaudelunn Rau. That's it. I don't have enough extra funds to finish my 1/48 line (VF-1A Max, Low Viz, and VF-1J Max, Miria, or VF-1S Hikaru).
