Have you considered trying to make one yourself?
I picked up the below Plates on holidays, Blue Curaçao one real and a lucky score but Red one homemade by a lad on a Cuban beach.
Note backside pic shows marks from the squared off bolts he was hitting w/ a hammer, I could've had something cool made but had to catch a bus so bought this one for a few Pesos.
It's far from perfect and you could do better w/ practise also if illegal, you may be making them for the State anyway so could run off a few real ones?
