Check with Gambers General Store
I'm not sure if they will have them, but if not they will know where you can get one if you can at all. The idea was devoloped by an ex-dealer from the LV Hilton and what I was told some years back is that he rents them each month (great idea if it's true).
Anyway give Gamblers General Store a call (in Las Vegas) and see what they can tell you.
