"You are not making any friends with the local RE agents in my opinion."

Are we supposed to be?

I say if it has missing insulation regardless of how it was found, the seller should replace it.

Any tool one can use or choose to use is at his own discretion.

I think once the price of the camera's drop down in price your going to see one in every toolbag in the future.

The only drawback is if you do have a camera and then you'd better not miss anything with it. The judge and jury won't understand why.

JMHO
