I work for sony electronics in a production facility that runs 24/7. It costs us >$500.00 a minute in profits when one of our production lines goes down on system failure. If it is a part that we don't happen to have in the parts system, we go with something like this.
If you think about losing $500. a minute, who cares if it costs $1000 to get it here today instead of tomorrow.
Above and beyond that, the place that we want the part from...wake them up and pay them to get us that part yesterday.
Things like this are life savers.
