I must lead a charmed life, because on reflection in 61 years of photography I have never had a camera that crapped out on me, and most of my cameras were bought second hand, although not from auction sites because I don't buy stuff I haven't had my hands on and tried out, having worked for more than 20 years in camera stores and testing second hand equipment that customers wanted to sell or part exchange makes me very reluctant to buy things sight unseen, when especially when I see the cameras on eBay that are described as mint that look like they have been used as hockey pucks.
