Managed to get my hands on an FCA3000 counter and after some testing and comparisons, I've opted to sell it. This counter is a rebadge of Pendulum's CNT-90, like the Fluke PM6690. The counter is near unblemished from a cosmetic standpoint and is both fully functional and is in calibration until January of 2019 (done by Tek themselves, I believe it's a former demo unit.) Also including a paper copy of the quick start manual, two software CDs (everything on them is downloadable, I believe), the cal certificate, and a power cable. Asking $900 US plus shipping - 13 lbs across the country to California is $31 and shipping insurance is $9 (1% of the declared value) via FedEx. Am willing to ship internationally, but it could get pricey and you'd have to cover any customs/import fees when it enters your country. I accept paypal, or we could arrange a local pickup (north of Washington DC in Maryland). This item has been sold.
Firmware is the latest version, no installed options so it has the standard timebase, but I've taken some measurements to show some of what the unit is capable of. The two input channels are specified to 300MHz, but I've clocked each at 590MHz - just the signal is significantly attenuated and there seems to be more noise in the readings.
For testing here's about a day worth of measuring a GPS disciplined rubidium source with the internal timebase (drift seems to be aligned with room temperature changes):
