The point was, either way if accurate calibration is
important you'll eventually have to send it off, whether it
be now or a year from now you still save money buying
something used (if it works properly otherwise) and having
it calibrated.

So yes it is something to be aware of, but not really
something to stop and think about particularly with used
gear since new gear also needs this done on the same
schedule, you're only putting off the first appointment in
that schedule.
