Good post, Milt, I agree 100%.
I have bought and sold a lot of items on this site without any significant problems. I did sell an instrument one time that I had not personally checked out (won't do that again), and the buyer called and said it did not work properly. I bought a new one from Aircraft Spruce and had it sent to him.
If I screw up it should cost me - that way the lesson sinks in (I still don't carry hull insurance on the plane).
