supply and demand is all it boils down to IMO; even if this chick is the only one around who wants one, if there's only 1 ice bori out there she likes that person can make her pay whatever they want for it.
so as far as investing in them, I would say no. there's precious few of them as it is and even if you do stock up on them, again the number of people actually seeking them is probably less than that. XDD
