Ironically, I've been trying to get this project sorted for year and have lost around $1000 dollars in paying for prints, molds, and prototypes.
The problem with doing runs of cast sabers is the startup cost it high because of mold making and then you need to have order sized in excess of 300 pieces in order for it to make the project worth it to the companies. I did the Maul saber, because you can cut that in half with two casts to each prop. But even doing so. I still have a number of Maul kits that haven't moved nearly as quickly as the Machined Aluminum FX kits I've done.
