To be honest, I wasn't planning on spending money on dreamies until after I'd bought everything else I needed for my town. A lot of villagers will come and go during this time, and I'm a bit apprehensive about having a dreamy and risking losing him/her while I'm still working on my town (which involves TTing).
I can definitely afford her with IGB which can be sold for TBT, but I'm not planning anything at the moment. I bet if you look around the site, you'll find someone else who will definitely want her as soon as she's ready to move out.
Sorry I can't be more helpful than that! Thank you for letting me know about her, though.
