Like I said, it was about as high as I was willing to go, considering that yes, Blue was harder to find than the others, so I understand it's a little rarer . . . I never really expected to find it for any cheaper than that, honestly . . . and if they are, it's usually because they're in really poor condition (dirty, torn, frayed, missing the little saddle/shell on the back, etc.)
Similarly, this is why I still don't have those Tyco figures of Herry or Rosita for my SS scale model, because likewise, since they're so rare and hard to find, anytime they do pop up on eBay, it's usually for nearly $50 or more - yeah, not paying that for a little three-inch PVC figurine, regardless of how rare or collectible it is.
