[time-nuts] Need for a document comparing time interval counters

I had a 53230 the last few years I worked for Agilent.
The oven oscillator in it is inferior to a 10811.
Its only claim to fame IMHO is that it can measure
Allan Deviation.  Turns out that we really needed
Hadamard, but it doesn't do that.  It is very expensive.
The old Santa Clara Division with the counter expertise
has now been gone nearly 20 years.  The counter line
has been offshored.  The expertise over there is
a complete unknown.

It had a "make offer" so I could not resist pointing out a new one is much less, and making a redicously low offer of $1000. I doubt it will be accepted,  but one never knows.  I once got a current Ketsight product for 2% of the current price,  so anything is possible.
