New power (True Cyborg)

This may have been attempted before, if so I apologize.
I'd like some opinions on it. Is it good, too much, or too little?

This power uses the Cyborg Creation rules on this site:

TRUE CYBORG

The hero with this power has a unique tolerance for acceptance of cybernetic devices. His (or her) body treats them as if they are body parts that the hero was born with. Typically this power is only discovered after the hero gains their first cybernetic device.

The hero gains three major benifits.

1] He adds the power rank number to his his cyber-threshhold for the purpose of gaining cybernetics (ex...everyone has a cyber threshhold rating of one hundred, if the hero has a TC rank of Remarkable then he would have a cyber threshhold rating of one hundred and thirty).

2] The Hero is immune to cyber psychosis (or the equivalent).

3] All cybernetic devices gained by the hero are treated as natural body parts and are treated as if they have a self-regenerating device included. They in no way detract from the Hero's natural healing.

As a power stunt the hero may add this powers power rank to his bio-threshhold (ex...If the hero has an Excellent Endurance Rank he would normally have a bio-threshhold of twenty. If he has a TC rank of Remarkable then his new bio-threshhold would be fifty).
