The problem is that all too often, board swapping does _not_ cure the
problem, or it introduces more problems, or... I have lost count of the
number of problems I've had to sort out that were made worse by somebody
(not necessarily a field servoid, it has to be said) replacing all
sorts of random parts.

Well, in my experience it's more a case of 'You'll be down for a day, and
then the machine will run for 5 years without problems' .vs. 'We'll be up
in an hour, but you'll have all sorts of problems afterwards, and you'll
probably keep on having to have another hour's fiddling every other week
or so'. Of course they don't tell you that last bit ;-)
