Was it Pony Toy-Go-Round? Man, I wanted to buy that whole store...
And the Southern Cross figures weren't toys, they were model kits (can't remember if they were by Arii or Imai, though). And they can't be THAT rare...I saw a bunch of them in January in Tokyo at, of all places, a used CD shop in the Kitasenju area.
As for Robotech...well, I dislike it, but it's a friendly dislike...kind of like your best pal's lame little brother. He's annoying as all hell, but if he weren't around, who would you make fun of?
