...You also might try to contact BlueWaterDiving on this forum; he's a SP tech and a G250 fanatic. He'll have the poppet.
LakeCountyDiver,
Take halocline's advice if your local shop is dropping the ball on getting your G250 serviced..
Red is a good guy; you may simply want to send him a PM and consider using him to service your G250 if you are not comfortable doing it yourself.
Good luck.
