PD100 motor? should have good power. MUST use the proper oil though... i'd be a bit skeptical about the state the motor is. apparently if the wrong oil was used even for 3 months it could cause irreversible damage. if it was taken care of, then the price is right.
even if to simply use the stronger PD100 rods for an AAZ project and then sell the other bits, it could be worth it. the injectors alone are about $450 new.
