Sorry you are nauseated.
All of my complex mechanisms have been to a camera tech after i purchased them. Many times the cost of the CLA/Repair was more the the "Value" of the camera.
All of my cameras function as they were designed to. I don't care what they look like.
If they get dropped, rained on, dragged against a rock or building, that is just natural use.
A dent, smash, scrape, does not equate....."Gone Forever".
ALL my cameras are still here.
Good Luck
