While looking for some minis for my current game, I found these nice people, Mirliton. They still own the rights to the European production of the old Grenadier molds. I've owned a couple of their sci-fi minis for my Cyberpunk games (never knew who had made them as I bought them in an ebay lot). Bit pricey, but their minis are good.

The only actual Cyberpunk minis they still make from the old Grenadier line is the Bozos.
