KCOP-TV reports that "computers are fast becoming a necessity in our lives, but how many of us know what to do when they break down? Can you trust that computer-repair person to properly diagnose and fix the problem - or will you be charged for unnecessary repairs? We took computers with minor problems to 10 repair stores in Los Angeles - from large chains to small mom-and-pop stores. We found that most were honest, though their prices varied greatly. But two shops tried to charge us big bucks for repairs we clearly did not need. The highlight of the investigation was one small shop where the mechanic not only fixed the problem, he did it for free."
