The Austron 1250 is a very close look alike to the hp-105 Quartz standard. A
decent quartz oscillator is certainly worth having besides the usual Tbolt GPS or
Rb type references. The Austron will certainly be a "quieter" signal then the
Tbolt or Rb oscillators for short (<1 to 10 seconds) averaging times.
Of course we all would like the lowest price. If the unit is truly working
properly, I don't think the price is too terribly high. The only major drawback
is the actual oscillator "can" inside the unit is a sealed device which I believe
is the Austron 1150A Sulzer unit. It makes repairing it, should it fail, harder
to do. However, it can be replaced with a hp-10811 type oscillator unit, having
similar characteristics, without too much trouble.
Consider that a hp-10811 oscillator can be had for between $50 and upwards to
$150, the $250 is not a bad price. Especially when you consider that the
hp-10811 is just the oscillator and would need the inclusion of a cabinet, power
supply and other supporting harware, etc., to achieve the same versitility of the
