[time-nuts] Question for the cesium nuts.

[Daun Yeagley]

A couple of years ago my wife dropped her digital camera in a parking lot at a
wedding we were attending.  The camera would turn on, but it complained that
there was no memory card.  When we got back home, I opened it up to find that a
surface mount dual transistor that controls power to the memory card had come
loose.  I thought it strange that this was the problem, considering how rugged
SM usually is.  After a lot of research, I was able to find out what the part
was and get a replacement. (NOT, of course from the camera manufacturer.. they
would only sell me the completed board at a cost exceeding the price I had
originally paid for the entire camera!).  Works fine again now.

My digital camera died recently.  (Well, it was killed.  I gave it a bath in 
salt water when I miss-judged a wave at the ocean.)

I went to the local brick and mortar camera store to get a replacement.  
After I told the guy what I was interested in, he brought out several 
possibilities.

He dropped one of them on the floor from normal hand/chest height.  It was 
still working after he picked it up.  I forget the brand, but somebody was 
willing to put their reputation on the line.
