I have a 01 golf alh with underboost. Actuator travel is not full when I run the VCDS test. I have ordered a mityvac tester but expecting bad vnt actuator. Should I stay away from the cheap/low cost ones eg on Amazon?

Are you sure it's the actuator? It could be sticking veins in the turbo. When you get your mityvac see if the actuator holds vacuum. If it does it's not the actuator. If it doesn't hold then it's the actuator
