Do you need it to be full-size? If I recall, the one in the movie was pretty large. If you don't mind a smaller version, the Noble collection used to offer one with Swarovski crystals. You'd have to check their catalog to see if they still have it.
I'm thinking scaled down for daily use. I would also prefer one from the RPF because I think its nicer to get something hand made or the thought that someone put time into the prop then a mass produced item.
I think because of the Noble collection and other official replicas, people replicating it themselves would be very few and far between. Infact I'm not sure I've ever seen anyone make their own :confused
