Tim, I have been to their facility near Gettysburg(actually Aspers) and you would be surprised as to who they supply. Even to overseas sellers. As a side note while they are not a retail outlet there, you can order supplies and pick it up there if you are in the area. Saves on shipping. They have also made up a custom set for me at no additional charge. They even helped me figure out sizes I was unsure of. Really nice people and surprisingly a smallish operation.
