Well I ordered mine from TR47 himself (he posts on here regulary and you can contact him directly). Another one I know who has been selling OT SW sets is Rikter, who also posts on here. You can send them PM´s and see what they have to offer. Go to their profiles and you can see the info there.
As far as I know the sets don´t come in cases with artwork. It´s a do-it-yourself kinda thing and I like that. You do the package according to your own taste.
