A Kaye Wiggs has been one of my grail dolls for a long time, so I understand your lusting!
I have wondered the same thing, but assumed they had to be paid in full and never went looking too far for a different (and more tempting) answer. You might find it at the ResinCafe, though. -

Oh, and as the owner of a JID boy, I can vouch for them as fantastic dolls to have. If you get a girl, you'll be able to sew most of her clothes, though, because other than direct from IH, there isn't a lot out there that fit their bigger, more mature bodies.
