What parts are you looking for? Most of the machines that had the HGP Hopper or Game plan hopper have been converted over to the newer style Hopper, HSH Hopper. Changing out or switching Hopper can be costly since your basically replacing the guts of the
changer. But if the
changer cabinet is in good condition it?s worth doing. The HGP Hopper went out of production about 10 years ago and most parts are no longer available, if you do find any except to pay a premium for them.
