B&H (no relation to Bell & Howell) has them listed in their catalog. 1-800-947-7785.
Gratuitous editorial: We tried this system when it first came out, because the storage is extremely compact compared to the Carousel trays. The projector has a terrible optical system, overheats the slides, curls cardboard mount and jams on plastic mounts. We quickly switched back to Kodak.
