I would push to get the price of a new one. Being that new, it will be very difficult to find a used one, and you will probably end up buying a new one. It's not right for you to have to settle for a different unit, or have to search all over and possible travel to get you replacement. You should be compensated for the hassle.
An attorney will probably get you new pricing, plus they will have to pay your attorney fees. I'd explain that to the adjuster, and tell him you want a check for the cost of new, or the next communication will be from the lawyer.
