I spoke with kevin @ CPR about the possibility of them re-running the SG plastics about a month ago.
when they run a set (for any machine), I believe their minimum is 60-80 sets. if marco's is willing to step up and order 30 sets like someone mentioned earlier, I'm sure that I can convince kevin to run them again. (I'll hold my NOS Joust playfield that he wants for cnc and dimpling positioning as hostage
seriously though, I'll make a few phone calls today to the appropriate parties and see if I can get the ball rolling.
with regard to the pop bumper caps, I spoke with steve young on this for both SG and SW about a month ago (when I approached him on running a set of the deep blue jeweled posts) and he stated that they didn't have set-up to perform the hot stamping around the bumper cap edges because it wasn't flat (although, I could have sworn seeing other bumper caps that they offer have something similiar)
