A quick look on 'fleabay' looks like just over the AUD1000, I recall I got mine for 800-900 AUD a year or so ago, but then the Aussie dollar was worth a bit more then, I haven't had any problems with the bigger Chinese sellers and they see to sell cheaper than the US sources. If you can get under the AUD1000 you can often not get slugged with GST if you are importing into AUS.
A good place to look is

I use an old HP GPSDO z3801 to get it up to accuracy.
Otherwise a good bit of gear , some programmes available to run it via HPIB via prologix adapter , programme AT
