I've debated getting one for the longest time. But there's always other things I want more at any given time, and you can get A LOT of stuff for the price of just one doll.
And once you have one, there's the matter of getting different outfits, maybe some accessories, new wigs, eyes, and before you know it you want more dolls to show off more of your collection simultaneously and of course, as friends to your first doll.
