I bought her the year she came out. She's an awesome prop. I wouldn't sell her for less than you purchased her, especially since she's rare and no longer made. She is probably one of my favorite Animated Witches that Spirit Halloween has ever sold.
I agree with Curve82, one of their best props that year, or ever, for that matter..don't remember what i paid, though, as I got her on day after halloween sale, I suspect it was probably $249 or $299 originally
