A FE10 where the shutter caved in. I sent it for repair and then sold it.
A F100 where the back door clips was broken due to rough handling of the bag the camera was in. I bought a new door and put it on.
A point and shoot Ricoh GR1 where the shutter seized to fire. Sent to Ricoh Germany for repair and they estimated the repair to cost 200 euros or 50 euros for them to send it back. I told them to keep it. This, the Ricoh, I haven't forgiven.
