The economy of the repair depends on how much you pay for it in the end I suppose and whether you tackle it yourself..
It is most likely that the drawers are either stuck or that the cords have come off of the pulleys. Not an easy task by all accounts to restring these but new parts are available as they are the same as for the BC9300.
If the problem is elsewhere then the cost of repair will obviously depend on this.
