There is one esablished store fixture dealers in the state of Idaho, Store fixtures of Idaho. They offer new Lozier, and mention they buy used products.
Craigslist (website), is sometimes a solid option for a local purchase.
The geography of Idaho limits your option when looking fo a good deal. The only major cities with a fair shipping lane are Seatlle and Portland, OR.
