$600 is the cheapest for NIB from Partzilla.  I'm hoping that someone has a lead on a junked bike.

There are some on ebay.  I seem to remember that the European 06-11 ZZR1400 ABS cluster is the same (apart from the white clock face) even tho the 09 ZG1400 has more to display ie, TPMS will show once the bike is ridden to wake it up - comparing the plug on the rear may show.

I went to Ebay and got a used cluster.  I plan on swapping the electronics since the used one has some dings and dents in the plastic.
